CME: 2023-12-31T22:00:00-CME-001

Actual Shock Arrival Time: 2024-01-03T14:19Z

Observed Geomagnetic Storm Parameters:
Max Kp: 3.0
CME Note: Fast partial halo CME with protruding narrower nose, seen in SOHO C2/C3 coronagraphs (fully covered by a data gap in STEREO A beacon); associated with X5 class flare from AR13536 near East limb. Coronal signatures include narrow ejecta seen in GOES SUVI 304 starting 2023-12-31T21:44Z and a wide EUV wave in AIA 193. Possible arrival signature is characterized by sharp jumping in B tot from 5nT to just under 10nT and increases in solar wind speed (from 425 km/s to ~490 km/s), density and temperature. DSCOVR is corroborated by ACE (despite large data gaps). The initial shock is followed after 2024-01-03T16:30Z by a smooth rotation of all three magnetic field components, indicating a flux rope. An hour later there is a similar arrival signature at STEREO A. Tentatively associating this arrival with 2023-12-31T22:00Z CME. Even though this might alternatively be 2023-12-30T09:36Z CME arriving, 2023-12-31T22:00Z CME is a likelier candidate bc of high speed at L1.

CME: 2023-12-31T10:00:00-CME-001

Actual Shock Arrival Time: 2024-01-03T04:50Z

Observed Geomagnetic Storm Parameters:
----
CME Note: CME NW in SOHO LASCO C2/C3 imagery visible for about three frames in STEREO A COR2 imagery prior to a data gap starting at 2023-12-31T10:53Z, after which the CME is out of the field of view. The source is a large filament eruption spanning N35W30 to N20W65 which begins to lift off around 2023-12-30T09:40Z as seen in SDO AIA 131, 171, 193, 304 imagery. Post-eruptive loops begin to form around 12:30Z in SDO AIA 171 and 193 as well. Most of the eruptive material appears to originate from the more western side of the filament. A possible arrival signature is characterized by an amplication of magnetic field with Btotal increasing from 7nT at 2024-01-03T04:50Z to ~12nT, an increase in solar wind speed from 415 to ~480 km/s, as well as a significant jump in density to over 18 pp/cm^3 and and increase in temperature are also observed. There is a likely arrival of the same CME at STEREO A hours earlier, indicating a westerly event.

CME: 2023-12-30T09:36:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: This CME is visible to the SE in SOHO LASCO C2/C3 and STEREO A COR2 imagery. Due to an ongoing STEREO campaign, this event is only visible for a few frames in STEREO A imagery. The source is a large filament eruption in the SE (spanning 30E30 to S40E70) which begins to lift-off around 2023-12-30T08:30Z as seen in SDO AIA 131, 171, 193, 304 imagery. Dimming is visible in SDO AIA 193 starting around 09:30Z, and post eruptive arcades begin to form around 10:00Z seen in SDO AIA 171 and 193. This event partially overlaps with CME: 2023-12-30T08:00Z. Event though there is an arrival at L1 at 2024-01-03T14:19Z the 2023-12-31T22:00Z CME is a much more likeliy candidate for this arrival, expecially based on the relatively high speed at L1.

CME: 2023-12-25T09:38:00-CME-001

Actual Shock Arrival Time: 2023-12-29T11:34Z

Observed Geomagnetic Storm Parameters:
----
CME Note: Very faint partial halo only seen in SOHO LASCO C2 and COR2A difference imagery (not seen in C3), with the likely source a sigmoid-shaped filament eruption centered around (N20E10) extending from N25E25 in the NE to AR 3530 (S08W10). The filament is seen erupting after 2023-12-25T07:20Z in SDO AIA 193 (as dimming and post-eruptive arcades) and 304 (as arcade footpoint brightening). Filament not seen in H-Alpha (but seen in AIA 211). Faint halo with slight east bias. Arrival Signature: Characterized by amplification in magnetic field components, with B_total reaching a maximum of 11nT at 2023-12-29T21:42Z. Accompanied by a minor increase in speed from ~360 km/s to ~390 km/s. Density data is speculative as there are discrepancies between DSCOVR and ACE, as well as data gaps. Prior to the arrival, there were several bumps in density around 2023-12-28T22:45Z, 2023-12-29T02:50Z, and 2023-12-29T08:45Z, possibly due to the preceding CME arrival from 2023-12-27T08:26Z.

CME: 2023-12-24T16:12:00-CME-001

Actual Shock Arrival Time: 2023-12-27T08:26Z

Observed Geomagnetic Storm Parameters:
----
CME Note: This CME is visible to the SW in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The source is likely a dimming region observed in SDO AIA 131, 171, 193 imagery starting around 2023-12-24T15:00Z from ~S25W45. Arrival signature: Likely but not characteristic CME arrival/sheath with magnetic field enhancement to just below 8nT, followed at ~2023-12-27T20Z by a likely start of a flux rope showing smooth rotation of magnetic field components and possibly indicating a glancing blow from a CME since components run in parallel. The arrival time might be even earlier since there is a data gap in DSCOVR from 2023-12-27T07:16Z to 08:26Z (also overlapping by an even larger gap in ACE data). This arrival could alternatively be attributed to the arrival of 2023-12-24T13:25Z CME.

----
CME Note: This CME is visible to the north in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The source is a large filament eruption spanning N45W20 to N35W55 which begins to lift-off, appearing to deflect northward, around 2023-12-24T12:45Z as seen in SDO AIA 131, 171, 193, 304 imagery. Post-eruptive brightening is also visible in SDO AIA 171 and 193 imagery starting around 13:30Z. Arrival signature: Likely but not characteristic CME arrival/sheath with magnetic field enhancement to just below 8nT, followed at ~2023-12-27T20Z by a likely start of a flux rope showing smooth rotation of magnetic field components and possibly indicating a glancing blow from a CME since components run in parallel.

Actual Shock Arrival Time: 2023-12-15T10:57Z

Observed Geomagnetic Storm Parameters:
----
CME Note: Partial halo seen directed towards the NW in all coronagraphs. Source is a C2.8 flare from AR 3514 which peaked at 2023-12-12T22:55Z, best seen in SDO AIA 131, and an associated dimming region starting at 2023-12-12T22:30Z best observed in SDO AIA 193/211. The dimming regions spans approximately W12->W26 and N11->S10, with the most dimming occurring centered around N06W19. A double ribbon flare/surface brightening is observed in this same region in SDO AIA 304, along with a small post-eruptive arcade that begins at the same time as the eruption. Clear arrival signature: A clear shock signature with a sharp increase in B total to initially 15nT and eventually to over 23nT, with rapid fluctuations of all magnetic field components. This is accompanied by a jump in solar wind speed at first from under 300 to 400 km/s, further increasing to just under 550 km/s and a sharp increase in ion density and temperature. There is also a matching arrival at STEREO A.

CME Note: Extremely faint partial halo CME in the NW in SOHO LASCO C2 difference imagery only. Its source might very tentatively be the mid-size filament eruption starting around 2023-12-11T22:01Z and centered around ~W05N05, just N of the central (equatorial) coronal hole.

CME Note: Southern directed CME as seen in LASCO C2/C3 and STEREO A COR2 imagery. Partial halo. Source is a faint and broad area of dimming spanning from about E20-W30 (near AR3489 to AR3498) starting at about 2023-11-22T20:45Z as seen in SDO AIA 171/193 and GOES SUVI 284 imagery. There was a C4.1-class flare from AR 3489 (S15E07) with peak time 2023-11-22T19:02Z associated with this event. Arrival signature is complex, with solar wind speed was jumping from 480 km/s to over 550 km/s, reaching a maximum near 600 km/s and a corresponding amplification of B_total from 7 nT to 18 nT and of density from 17 to over 25 particles/cc. The signature is complicated by the preceding arrival of a coronal high speed stream on 2023-11-24.

CME Note: CME visible in the NW of SOHO LASCO C2/C3 and STEREO A COR2. Source is seen as dimming centered around N15W15 starting around 2023-11-16T00:34Z in SDO AIA 193. This eruption is also seen in STEREO A EUVI 195 imagery near disk center. Overlaps in the field of view of the coronagraphs with CME: 2023-11-16T04:24Z, which is believed to have originated on the back side. Arrival signature: Characterized by a jump in B_total from around 5.6 nT to a peak of 14.55 nT, with Bz remaining largely neutral with a short southward spike to -5 nT. An increase in density and small spike in temperature and solar wind speed to about 340 km/s are also observed. A separate enhancement in the magnetic field components, possibly associated with the same CME event, is observed leading up to this event seen best from 2023-11-20T05:00Z onward with a gradual increase in B_total up to around 12 nT. Around 2023-11-20T09:12Z, Bt swiftly drops down to around 5-6 nT prior to this arrival.

CME Note: Faint and wide CME seen to the west in SOHO LASCO C2, C3, and after a data gap in STEREO A COR2 in difference imagery. There appears to be a shock and bulk portion to this CME, with the shock exhibiting more of a dimpled front, possibly due to an emerging feature to the NW overlapping the upper left-hand portion of the CME. This doesn't appear to impact the trailing front or "bulk" portion of the CME. The source of this CME appears to be an eruption in the southwest quadrant of the Earth-facing disk near Active Regions 13484, 13477, and newly numbered AR 13485. Noticeable moving/opening field lines are seen in SDO/AIA 193, 211, and GOES SUVI 284 starting around 2023-11-10T18:34Z. Dimming is also visible in SDO/AIA 211 starting around 2023-11-10T19:29Z with wide and brief potential post-eruptive arcades visible in SDO/AIA 193 starting around 2023-11-10T21:00Z.

Observed Geomagnetic Storm Parameters:
----
CME Note: This CME is visible to the south/southwest in SOHO LASCO C2, C3, and STEREO A COR2 imagery. The source of this CME is a filament eruption stretching between S18E00 to S40E40. The filament begins to erupt around 2023-10-31T20:00Z as seen in SDO/AIA 304 with clear deflection to the south/southeast towards disk center before exiting the SDO/AIA field-of-view. Brightening, moving/opening field lines, and a wide-set post-eruptive arcade are visible following the eruption of the filament in SDO/AIA 193, 171, and 304. Likely arrival signature is characterized by a rapid amplification of magnetic field with Btotal increasing from 5nT at 2023-11-04T15:45Z to 16nT at 16:57Z. A significant increase in density is observed as well. Further review of this arrival signature in consultation with Lan Jian at NASA/GSFC suggests that this arrival may be associated with CME: 2023-10-31T22:12Z. It is possible that the B rotations in late Nov 4 at the WIND spacecraft are due to the same CME.

CME: 2023-10-16T12:09:00-CME-001

Actual Shock Arrival Time: 2023-10-20T07:30Z

Observed Geomagnetic Storm Parameters:
Max Kp: 5.0
CME Note: Bright CME seen to the NE in SOHO LASCO C2/C3 and STEREO A COR2. Source is C7.5 class flare starting at 2023-10-16T10:31Z and associated eruption. The flare can be best seen in SDO AIA 131/193, opening field lines are visible in SDO AIA 171/193, and dimming and post eruptive loops are also seen in SDO AIA 193. Arrival Signature: Characterized by a weak amplification of magnetic field components with Btotal reaching 10nT at 2023-10-20T12:38Z. Subsequent increases were observed in density and temperature. This was followed by a rotation in magnetic field components during which an extended period of negative Bz was observed from around 2023-10-20T17:30Z to 2023-10-21T08:00Z. This arrival signature may be reflective of a weak arrival/glancing blow from CME: 2023-10-16T12:09Z.

CME: 2023-10-14T14:00:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
Max Kp: 3.67
CME Note: This very faint NW CME is barely seen in C3 and is completely covered by a data gap in COR2A. Its source is an eruption in AR 3466 (N09W27), seen as dimming around the AR and as post-eruptive arcade mostly to the NNW of the AR, as seen in AIA 193/304 starting 2023-10-14T13Z. Arrival signature was analyzed by Tarik Mohammad, LASSOS team: there is likely a SIR signature on 2023-10-18: a shock driven by this SIR (an increase in proton density, bulk speed, and ion temperature). There is likely no sheath region seen after the SIR signature: following the shock, you see the compression region with increased proton density, and bulk speed (the speed is gradually increasing and so is ion temperature). After that, we are in the high-speed stream with lower proton density and enhanced ion temperature.

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
Max Kp: 3.67
CME Note: Slow partial halo CME in the NNW with the source a gradual eruption of a long filament stretched between 15 and 40 degrees longitude along the latitude of 36 degrees N. The eruption is marked by post-eruptive arcades and relatively minor dimming along the filament channel, as seen in AIA 193 and 304 starting after 2023-10-14T04Z. Regarding arrival signature from Tarik Mohammad, LASSOS team: there is a SIR signature early on 2023-10-18 - a shock driven by this SIR (marked by an increase in proton density, bulk speed, and ion temperature). There is likely no sheath region seen after the SIR signature: following the shock, you see the compression region with increased proton density, and bulk speed (the speed is gradually increasing and so is ion temperature).

CME: 2023-10-02T18:24:00-CME-001

Actual Shock Arrival Time: 2023-10-05T21:25Z

Observed Geomagnetic Storm Parameters:
Max Kp: 3.33
CME Note: Extremely faint CME with uneven front seen to the east in SOHO LASCO C2 and COR2A. Source is very uncertain but one low confidence candidate is an area of very subtle dimming seen at 2023-10-02T16:54Z in SDO AIA & GOES SUVI 195 spanning from about N05E22 to N05E00(AR 13453) down to S10E00. Centered at about S05E10. This dimming is possibly associated with a C-class flare and small eruption from AR 13450 (S10E07) seen starting at 2023-10-02T15:54Z. A possible weak arrival starts around 2023-10-05T21:25Z and is characterized by rapid increase in wind speed from 430 to 490 km/s, some gradual increase in magnetic field strength from 5 to 9 nT, density increase from 3 to 14 particles/cc, and relatively small decrease in temperature. Field rotations follow around 2023-10-0617:00Z; there is a small increase in GOES >1 MeV channel at the same time that seems to support a CME arrival.

CME: 2023-09-22T22:24:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: Bright CME seen nearly due south in SOHO LASCO C2/C3 and STEREO A COR2 imagery; the CME is likely associated with an M1.9-class flare and subsequent eruption from Active Region 13435 near center disk (N07W01) with an erupting magnetic loop, coronal spray, and series of brightenings from near the active region footpoints seen best in SDO 193 and 304. May partly be associated with a stray and faint erupting loop seen far off the southwest limb in SDO 171 near 2023-09-23T21:00Z but the timing of which the CME is first seen seems to be more likely in response to the center-disk eruptive signature. No clear arrival signature detected, although there is a relatively minor change in magnetic field on 2023-09-26T04:29Z and another one on 2023-09-26T10:58Z (but these signatures were determined inconclusive/minor).

Observed Geomagnetic Storm Parameters:
----
CME Note: Faint CME seen to the NNW in SOHO LASCO C2/C3 and STEREO A COR2. The CME fades away quickly in SOHO LASCO C3 imagery, and the leading edge is diffuse. Source location is likely an eruption centered around N27W02 starting around 2023-09-22T06:00Z best seen as dimming in SDO AIA 193. Arrival signature: sharp amplification of magnetic field to 27nT and increases in solar wind speed from ~300 km/s to ~500 km/s, with subsequent increases in density and temperature. Alternatively, this could be the arrival of 2023-09-14T07:24Z CME or possibly the combined arrival of these two CMEs.

CME Note: CME seen to the NE of SOHO LASCO C2/C3 and STEREO A COR2. Source is a filament eruption near AR 3435 (approximately (N08E17). The liftoff can be seen starting around 2023-09-22T01:28Z in SDO AIA 193/304. There is also an M1.2 flare just after the start of the filament eruption from this AR starting at 2023-09-22T02:25Z, followed by post-eruptive loops best seen in SDO AIA 131/193. Brightening can also be seen in this region in SDO AIA 304. Arrival signature: sharp amplification of magnetic field to 27nT and increases in solar wind speed from ~300 km/s to ~500 km/s, with subsequent increases in density and temperature. Alternatively, this could be the arrival of 2023-09-22T07:36Z CME or the combined arrival of these two CMEs.

CME: 2023-09-18T12:09:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: Ear-shaped partial halo CME in the NW (or two CMEs moving in unison), with no clear source found, so it is likely backsided. To support the backsided assumption, there seems to be a faint opening of magnetic field lines/restructuring of magnetic field seemingly far behind the NW limb seen in GOES SUVI 284 around 2023-09-18T12Z. Although there is no clear front-sided source, there seems to be minor flaring in AR 3433 (delayed to a plage) and AR 3429 and there is seems to be a post-eruptive arcade that fills a dark filament channel W centered (N10W50) of AR3439 by 12:55Z. There is also a very minor eruption on the NW limb N of AR 3225(N23W81) starting at in AIA 304. These are very minor coronal signatures though. There are no CME arrival signatures at L1 on September 22-23 and the second half of 21.

Actual Shock Arrival Time: 2023-09-18T12:58Z

Observed Geomagnetic Storm Parameters:
Max Kp: 7.0
CME Note: Wide, complex, difficult to analyze CME with primary directionality (bulk) to the southwest in SOHO and STEREO A coronagraphs but containing features also seen to the west, south, and southeast along a discontinuous front. Associated with a large-scale filament eruption taking place on the Earth-facing disk from 2023-09-16T07:00Z to 09:00Z seen best in SDO/GOES 304; filament extends from N30W00 southwest through N10W30 with a minor, more narrow segment extending back east from N10W30 back towards S03W05. Arrival signature: Sudden sharp jump in solar wind parameters with B total reaching 21 nT and speed increasing above 550 km/s. May be indicative of additional coronal hole high speed stream influences (Tarik Salman, LASSOS team) from coronal hole at central meridian on 2023-09-15. Less likely but possible that this is a combined arrival of this CME and the 2023-09-14T23:12Z CME.

CME Note: Bright CME NW in SOHO LASCO and STEREO A COR2 that may be associated with a faint partial to full halo. The source is a filament eruption seen between AR's 13425 & 13423 stretching from ~N22W40 to ~N26W55. Eruption begins ~2023-09-14T06:40Z in SDO/AIA 304 followed by brightening at the foot points of the source location. Associated dimming, minor EUV wave, moving/opening field lines, and post-eruptive arcade are visible in most SDO/AIA wavelengths including 193, 171, 211, and 131. The visible dimming is seen primarily north of the filament location with the minor EUV wave primarily seen along the W/NW limb in SDO/AIA 211. An M-class flare is associated with the post-eruptive arcade occurring between AR's 13425 & 13423. Arrival signature is characterized by a relatively modest jump in ion density and temperature, as well as in magnetic field, with B total reaching 8nT. Preceded by a relatively gradual increase in solar wind speed from 400 to 480 km/s.

Observed Geomagnetic Storm Parameters:
----
CME Note: Partial halo seen in SOHO with clearer fronts more to the South and the NE. Its source is possibly the eruption of a long filament from NE to SW and centered around N15W15 seen in AIA 193/304 starting 2023-08-30T20:30Z, with post-eruptive arcades and dimming extending towards SE and encompassing the disk center. No clear CME arrival observed. However, there may be a weak arrival combined with the high speed stream observed at L1 on 2023-09-01 or 02. The flux rope is possibly seen in the solar wind magnetic field components, accompanied by a drop in temperature, around 2023-09-02T18:00Z. Overall this is a weak arrival signature.

Observed Geomagnetic Storm Parameters:
----
CME Note: Ultra-faint CME seen primarily to the south and west, especially in SOHO LASCO running difference imagery after 2023-08-23T23:00Z. Likely associated with the M1.1-class flare from Active Region 3405 (N10W32) and sympathetic structure of U-shaped dimming seen south and east of the active region, possibly centered around S10W20. Analysis and modeling of this CME is very uncertain and speculative given current geometry of available observing spacecraft, data gaps, and faintness of the CME. No clear evidence of arrival.

CME Note: This CME is visible to the NW in SOHO LASCO C2 and C3, as well as in STEREO A COR2 difference imagery. This CME overlaps with the CME first seen to the NW in SOHO LASCO C2 at 2023-08-18T19:48Z. The source of this CME is a C3.0 class flare from AR13409 (~N21W42) and associated filament eruption. The filament appears to have two parts erupt, an initial little arch of filament material related to the start of the flare and a more thick stream of filament material lifting off while the flare is nearing its peak. This is best seen in GOES SUVI 304, but is also visible in SDO/AIA 304 and 193 imagery. There is no obvious arrival across all solar wind parameters.

Observed Geomagnetic Storm Parameters:

CME Note: Wide CME seen W and S in SOHO and STEREO A associated with long duration M1.6-class solar flare/filament eruption near S10W68. Faint shock presents as a full halo with preference towards the west. Around 2023-08-05T06:45Z, a dark filament near the western portion of the disk is seen lifting off, becoming a bright structure as it leaves the disk towards the west. A somewhat unclear arrival signature, affected by low quality solar wind data from both DSCOVR and ACE during this time period. Arrival signature: initial increase in B_total from 7.4 nT to 10.5 nT, followed by another increase to 13.6 nT at 11:54Z. The signature looks like a messy sheath arrival and it is possible that there is a flux rope/magnetic cloud at ~2023-08-08T01Z but this could be another CME arrival (LASSOS team). The current arrival may also have been observed at STEREO A around 2023-08-07T08:46Z. Alternatively, this could be the combined arrival of 2023-08-04T04:17Z and 2023-08-04T04:49Z CMEs.

CME Note: Second of two CMEs seen to the north and west in SOHO/STEREO A imagery starting around 2023-08-04T04:17Z which is inferred to be in association with a long duration M1.9-class solar flare near the vicinity of Active Region 3386 (N12W46) due to the complex, sympathetic eruptive signature containing multiple areas of dimming. The CME front seen first near 2023-08-04T04:49Z appears to be embedded within the first, and is directed more westerly. Please see DONKI entry for additional details on the event signature. Arrival signature: Likely an arrival of a flux rope at L1, associated with an increase of B total to over 10nT, with rotation of magnetic field components. Confirmed by the LASSOS team.

CME Note: This CME is first seen to the NE in SOHO LASCO C2 at 2023-07-31T23:36Z in both white light and difference imagery. The source of this CME is likely the northern portion (from N15 to S10) of a filament which erupted at central meridian and seems to have deflected to the NE as seen in UV imagery. The northern portion of the filament seems to lift off at about 2023-07-31T17:30Z, as seen in SDO AIA 304 (though, it is difficult to discern exact time due to having only a face-on view of the solar disk). This CME overlaps with a prior CME which likely has a source on the far side of the solar disk. Arrival signature: Rapid magnetic field enhancement from 10 nT to 15-16 nT starting around 2023-08-04T06:52Z with simultaneous increases in solar wind velocity and temperature parameters. Possibly merged with 2023-07-31T23:12Z CME.

CME Note: Faint CME seen as a partial halo to the SW in SOHO LASCO C2, C3, and STEREO A COR2 imagery. This feature overlaps multiple CME fronts to the SW. The source appears to be the southern portion of a large North-South s-shaped filament eruption along the central meridian of the Earth-facing disk. The southern portion of this filament appears to potentially lift off at about 2023-07-31T19:05Z roughly centered around S22E02. The northern portion of the filament eruption may be associated with another CME feature seen in the coronagraphs to the East. Arrival signature: Rapid magnetic field enhancement from 10 nT to 15-16 nT starting around 2023-08-04T06:52Z with simultaneous increases in solar wind velocity and temperature parameters.

CME: 2023-07-28T15:53:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: Fast CME in the NW following the associated M-class flare from AR3376 behind the limb (N25W99) and the associated bright magnificent eruption seen just behind the limb in AIA 131/304/193 in the NW starting around 2023-07-28T15:45Z. We can see the rotating flux rope in coronagraphs. There is also a more halo-like fainter shock which is likely backsided. Glancing blow at L1 is unlikely because the CME is either on limb or backsided, so arrival at L1 2023-08-01T10:08Z was attributed to a much more likely front-sided 2023-07-28T22:36Z CME.

Observed Geomagnetic Storm Parameters:
----
CME Note: Halo CME with shock front preceding the brighter bulk. Its source is likely an eruption in AR3376 (N23W34) starting after 2023-07-23T14:00Z, likely associated with the C5.2 class flare from AR 3376 (N23W34) peaking at 2023-07-23T14:57Z. There also was a C7.4 class flare from AR 3372 on the NW limb at the time that has to be considered. Arrival signature: Interplanetary shock characterized by rapid magnetic field enhancement from 6 nT to 17 nT, rapid velocity increase from ~390 km/s to 550 km/s, and accompanying density increase. Flux rope may have started closer to 2023-07-26T03:44Z.

Actual Shock Arrival Time: 2023-07-21T19:25Z

Observed Geomagnetic Storm Parameters:
----
CME Note: The source of this NE CME is likely an eruption and M1.4 flare from AR 3376 (N27E35) starting ~2023-07-18T19:25Z as seen in SDO AIA. This event partially overlaps with CME 2023-07-18T20:36Z. Arrival signature: from Tarik Mohammad (LASSOS team) a well-defined shock (increase in magnetic field strength, proton density, and bulk speed). A possible sheath region following the shock (enhancements in all the parameters). The possible ICME ejecta start is ~2023-07-21T22:20Z: rotations in both B_y (positive to negative) and B_z (negative to positive) and a sharp decrease in proton density and decrease in bulk speed and temperature. Possibly flank CME encounter since the components (specially B_x and B_y) remain constant. The end of the ICME ejecta is difficult to determine as we have a trailing high-speed stream. The possible end is around 2023-07-22T06:00Z.

Observed Geomagnetic Storm Parameters:
----
CME Note: Halo CME seen primarily to the southwest in association with two separate M5.0+ class solar flares and a strong eruption from Active Region 3633 (S25W73). The eruption is proceeded by another eruption which is impressive in itself; the main eruption starting around 23:18Z as seen in SDO 131 imagery is characterized by a very large scale brightening near Active Region 3363 with rising plasma along the southeastern portion of the active region, widely and quickly moving and opening magnetic field lines seen in SDO 193/171, and a strong post-eruptive arcade signature characterized by intense, regional brightening along the southwest limb in SDO 131. Associated with SEP events at SOHO, GOES, and STEREO A. Arrival signature: A jump in solar wind speed from 330 to 440 km/s, accompanied by a jump in B total to just under 12 nT, an increase in density and rotation of magnetic field components.

Observed Geomagnetic Storm Parameters:
----
CME Note: CME is faint and difficult to observe, seen as a partial halo to the S/SW in SOHO LASCO C2 and for few frames in STEREO A COR2 preceding data gap. The source is likely an eruption and subsequent C8.8 flare from AR 3370 (near S18E14) starting around 2023-07-14T18:35Z as seen in SDO AIA 131, 171, 193, 304 imagery. Noticeably deflected W. Arrival signature: Sharp increase in B-total from 7nT to 13nT. Sudden fluctuation in B-field components and increases in solar wind speed from ~350km/s to ~450km/s, in temperature and gradual increase in density. From Tarik Salman, LASSOS: definite shock arrival ~2023-07-16T18:35Z and another similar and more prominent feature in the plasma data around 2023-07-17T01:26Z (speed jump of 200 km/s) but nothing in the magnetic field. It is possible to have an admixture of HSS as well late on 2023-07-17.

Observed Geomagnetic Storm Parameters:
----
CME Note: This CME is visible to the SW in SOHO LASCO C2, C3, and STEREO A COR2 imagery (data gap during event in STEREO A as it travels out in the field of view). The source of this CME is a double ribbon flare near AR13366 and plage region 13358 and associated filament eruption starting around 2023-07-10T03:20Z. The eruption is most clearly visible in SDO/AIA 131, 304, and 171. The associated filament is very clearly seen in GOES SUVI 304 as well. Arrival signature: Clear interplanetary shock consisting of magnetic field enhancement from 7 nT to 14 nT, rapid increase in ACE particle density, and rapid but relatively small increases in solar wind speed and temperature.

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: [PRELIMINARY] This CME is a very faint potential partial halo seen to the SE in SOHO LASCO C2 difference imagery. The potential source of this CME is the filament eruption/double ribbon flare and associated brightening and dimming seen to the SE near AR's 13358 and 13359 starting around 2023-07-06T05:36Z. A post-eruptive arcade is visible between 06:00Z and 07:00Z. Due to the faintness of this event, high speculation is present. No clear arrival detected across all solar wind parameters, but we are checking with LASSOS team.

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: Complex partial halo CME comprised of multiple embedded fronts seen mostly south in SOHO/STEREO A coronagraphs but brightest in STEREO A COR2. The CME appears to contain a wide bulk and a very wide faint shock present in the northeast. Likely associated with an eruption near the vicinity of AR3359 (S22E24) seen best as a spray in SDO 193/171 starting shortly before 03:00Z as well as large-scale brightening in SDO 304 seen near 04:00Z. A broad area of large-scale post-eruptive arcades are seen back towards the northeast after the eruption, particularly in SDO 193. Data gaps due to a STEREO A campaign limits analysis of this event. No clear CME arrivals on July 6-8.

Actual Shock Arrival Time: 2023-06-29T08:20Z

Observed Geomagnetic Storm Parameters:
----
CME Note: There was a significant SOHO data gap during initial real-time analysis of this CME. This CME is visible to the N/NE in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source appears to be a filament eruption visible to the NE in SDO/AIA 304 with associated dimming signature in SDO/AIA 193, and moving/opening field lines visible in SDO/AIA 171. The filament is slow to fully erupt, potentially causing multiple fronts to appear in the coronagraphs. Arrival signature is weak, possibly indicating a glancing blow CME arrival, characterized by separation of magnetic field components, increase in speed and magnetic field intensity from 5 nT to 8 nT and a temporary drop in temperature.

Observed Geomagnetic Storm Parameters:

CME Note: Large CME visible to the East in SOHO LASCO C2, C3, and STEREO A COR2. The source of this CME is the X1.1 class flare from AR13341 peaking at 2023-06-20T17:09Z associated with a widespread EUV wave from the Eastern side of the disk towards the central meridian of the Earth-facing disk (best seen in SDO/AIA 211 and 193), as well as dimming (visible in SDO/AIA 193) directed towards the NW of the source location. A post-eruptive arcade follows the eruption which is best seen in SDO/AIA 171 starting around 2023-06-20T17:45Z. From Tarik Mohammad, LASSOS: There is an arrival of HSS on June 23. I doubt that we see a CME arrival in late June 24. The field components look similar (especially B_y) before and after the approximated arrival. The higher magnetic field strength can occur due to some form of compression (seems like the average speed in this interval is higher than the previous).

CME Note: This CME is visible to the SE in SOHO LASCO C2 and STEREO A COR2. The source is likely the associated M2.5 flare to the east of AR 13331 (S22E48, east of AR location of S22E38) and the associated eruption seen in SDO AIA 131, 171, 193, 304 imagery. An opening of field lines is visible in SDO AIA 171 and 193 imagery, with dimming seen even more to the East of the flare (and AR) location after 2023-06-09T17:08Z and post-eruptive loops starting to form around 2023-06-09T18:00Z. Update: This CME may have been detected at STEREO A on 2023-06-13T08:00Z, but we do not believe a signature was observed at L1 by ACE or DSCOVR.

CME: 2023-06-07T07:00:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: CME seen to the southeast in SOHO LASCO and STEREO A COR2 which is associated with a quickly ejecting filament eruption from a minor filament sitting just under AR3327 seen best in GOES 284 and SDO 193/171/304 with liftoff around 2023-06-07T06:30Z. The eruption has two footpoints, one closer to AR3327 (S25E42) and one centered around S30E30. The arrival signature starting on 2023-06-10T23:09Z is likely a stream interaction region, not an iCME. It is characterized by a sharp jump in B total, accompanied by shock-like fast oscillations of magnetic field components. Plasma parameters are not indicative of a CME arrival: a very gradual increase in solar wind speed (300 to 400 km/s) and no shocks in density and temperature. There also may be SSBC around the start of 2023-06-11. From LASSOS team discussion: this appears to be a SIR.

----
CME Note: CME seen to the southwest in all coronagraphs (SOHO LASCO C2/C3, STEREO A COR2). Leading edge is faint and wide. Source is a large filament eruption seen spanning from about S32W10 to S10W50 in SDO AIA 304 starting at about 2023-06-04T09:00Z (Centered at S25W30). Post-eruptive dimming can be seen in SDO AIA 193 along the southwest quadrant of the Sun at 09:27Z, and ejecta can be seen off the southwest limb in SDO AIA 171 at 09:42Z. The filament can also be seen erupting in STEREO A EUVI 195/304 starting at 08:25Z/8:15Z, respectively. From LASSOS team discussion: this signature is likely a flank arrival of a CME passing West of Earth.

CME: 2023-05-30T17:12:00-CME-001

Actual Shock Arrival Time: 2023-06-03T21:05Z

Observed Geomagnetic Storm Parameters:
----
CME Note: Faint, slow, loop-like CME seen to the west-northwest in SOHO C2, C3 and appearing slightly brighter in STEREO A COR2 in the same direction. The source is unclear, and thus simulation results are fairly speculative, but measurements indicate some confidence in an Earth-facing source on the Sun between longitudes 20 and 30 degrees. Possibly associated with brightening and dimming seen on the Earth-facing disk early on 2023-05-30 near N00W40, or with a minor eruption near the vicinity of AR3319 with westward deflection. Arrival signature: increase of magnetic field and rotation of components. From LASSOS discussion: there could be two CME arrivals in this signature - one late on 6/3, then another on 6/4 lasting into 6/6, with the interaction region between the two CMEs around 2023-06-04T19:30Z.

CME Note: CME associated with an M3.9-class flare from Active Region 3296 seen to the northeast in SOHO and STEREO A coronagraphs comprised of a brighter bulk to the southeast and faint, wider shock with matching leading edge extending from the southeast to the northeast. A halo-like feature closely trailing behind this CME seen in COR2 running difference imagery may be associated with the eruption, but this is uncertain. A SOHO data gap exists over the CME propagation in the C2 FOV of view, obscuring analysis. Halo CME associated with M2.1 flare from AR13296 (N15E30). From LASSOS team discussion: Arrival on 5/7 is indicated by a sheath crossing and high field strength. No flux rope is observed in this signature.

Observed Geomagnetic Storm Parameters:
----
CME Note: Bright CME visible in the NE of SOHO LASCO C2/C3 and STEREO A COR2 imagery in SWPC_CAT. The source eruption starts around 2023-04-30T19:00Z in the vicinity of AR 3289 (approximately N20E25) and AR 3292 (approximately N15E30) and can be best seen as opening field lines, faint EUV wave, and some post eruptive arcades in SDO AIA 193. Opening field lines can also be seen on the limb in SDO AIA 171/193. The eruption is also visible in the NE of STEREO A EUV 195 imagery. Only based on field components due to suspect temperature/density data, ACE/DSCOVR may have observed a glancing blow of this CME starting around 2023-05-03T09:12. This corresponds to the start of an extended period of smooth field components but little rotation. A potential end of this CME can be 2023-05-05T06:05.

Observed Geomagnetic Storm Parameters:
Max Kp: 4.0
CME Note: Faint CME visible in the N/NE of SOHO LASCO C2/C3 and in the N/NW of STEREO A COR2. The source is a filament eruption seen lifting off in SDO AIA 304 starting around 2023-04-15T10:00Z. Dimming is also observed in SDO AIA 193 and STEREO A EUVI 195. Arrival occurs near 2023-04-19T09:22Z with extended rotations in the By and Bz magnetic field components as observed by ACE/DSCOVR. This might mean a crossing between the nose and the flank (more towards the flank). The plasma signatures are not very straightforward. This can be because the ICME arrives at the back of the SIR or because of the flank crossing. The possible end of the ICME is 2023-04-21T05:14Z.

CME: 2023-03-30T21:12:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: Minor, faint, but wide eruption first seen in SOHO LASCO C2 at 2023-03-30T21:12Z in the southwest, visible in both the SOHO and STEREO A coronagraphs. The source appears to be associated with a minor eruption from AR3262 located near S19W40 and dimming seen best in SDO 193, though the CME's leading edge quickly disappears before exiting the field of view, and the CME itself is too diffuse to reliably pair images between SOHO and STEREO A well. As such, there is significant uncertainty in the width and velocity parameters associated with the measurements.

Actual Shock Arrival Time: 2023-03-23T09:10Z

Observed Geomagnetic Storm Parameters:
----
CME Note: Bright, wide and asymmetrical shape CME seen to the NE in SOHO and STEREO A coronagraphs. The eruption is characterized by an erupting sigmoid/S-shaped structure centered around N27E20, though dimming and an EUV wave signature is limited to longitudes closer to 30-50 degrees east. On arrival signature from Tarik Salman, LASSOS: background solar wind is quite different from normal levels with higher density (normal density around 5/cc) and speed (normal speed around 350-400 km/s)-a possible reason for this ICME not to have an associated shock. The start of the magnetic flux rope likely coincides with the enhancement in the total field and drop in density and the end of it is around 2023-04-24T09Z (based on an increase in temperature beyond this point and the field components becoming less coherent)

Observed Geomagnetic Storm Parameters:

CME Note: Faint, wide CME to SW in SOHO LASCO C2 imagery during STEREO A data gap and campaign with limited imagery. Likely associated with a broad area of coronal restructuring, coronal dimming, destabilization, and filament eruptions seen in SDO 193, 304 starting ~2023-03-20T01:53Z between S10 to S30, W05 to W30. Arrival may be associated with CME 2023-03-20T14:42Z. From Tarik Mohammad, LASSOS: start of sheath is ~2023-03-23T05Z - enhancements in total magnetic field/density. Background solar wind is quite different from normal levels with higher density (normal density around 5/cc) and speed (normal speed around 350-400 km/s). This can be a reason there is no shock. Start of the magnetic flux rope ~13:30Z coincides with enhancement in total field and drop in density. 2023-03-24T06:50Z is the possible end time based on an increase in temperature beyond this point and the field components becoming less coherent.

CME Note: [PRELIMINARY] This CME overlaps the CME first seen in SOHO LASCO C2 at 2023-03-17T10:30Z to the SW. There are currently ongoing campaigns impacting the amount of available imagery for the SOHO LASCO C3 and STEREO A COR2 coronagraphs. The source of this CME is a large filament eruption seen in SDO/AIA 304 and GOES SUVI 304 starting around 2023-03-17T08:50Z with full lift off by 2023-03-17T12:17Z. The filament has it's largest mass centered around S40W30, but stretches between the longitudes of 0 degrees to 40 degrees and the latitudes of -20 degrees to -50 degrees. Possible minor arrival signature includes gradual increase of total magnetic field to over 11 nT with rotation of at least two magnetic field components, possibly indicating a CME arrival/glancing blow. It is likely embedded in a HSS. Waiting for assessment from LASSOS team.

CME Note: CME seen to the NW in STEREO Ahead COR2 coronagraph associated with a filament eruption seen near N30E02 which erupts with significant deflection to the north and west as seen in SDO/GOES 304 imagery around 2023-03-13T09:54Z. Arrival signature notes: this arrival could alternatively be attributed to a predicted glancing blow from 2023-03-12T19:24Z CME, although this is less likely due to the earlier arrival at STEREO A. LASSOS discussion summary about this signature: this is likely a strong glancing blow from a CME, with a sheath and a shock-like structure.

Observed Geomagnetic Storm Parameters:
----
CME Note: CME going South in SOHO LASCO and SSW in STEREO A COR2. Its source is a gradual eruption of complex, mostly longitudinally oriented filament centered approximately around ~S25E20 (filament seems to extend from at least S5 to S50) and is seen starting to erupt in AIA 304 and 193 around 2023-03-12T18:30Z. Possible arrival is marked by an increase in B_total from 8 nT to 22.5 nT, reaching a maximum of 26 nT at 2023-03-15T05:02Z. Accompanied by an increase in speed from approximately 420 km/s to 550 km/s, an increase in density, and increase in temperature. This arrival could alternatively be attributed to a predicted glancing blow from 2023-03-13T10:53Z CME (possibly more less likely due to the earlier observed arrival at STEREO A). LASSOS discussion summary about this signature: this is likely a strong glancing blow from a CME, with a sheath and a shock-like structure.

CME Note: Very faint CME in the NW in both coronagraphs first seen after the end of the nighttime data gap in STEREO A COR2. The start is currently covered by the data gap in SOHO LASCO but it is also faintly seen in C3 after this gap. One possible (front-sided) source could be a relatively minor eruption seen after 2023-02-28T06:19Z in AIA 304, 171, 193. In SDO AIA 304 there is a bright flare, then dark material (possibly ejecta). Brightening then dimming of area seen in GOES SUVI 284. It could be associated with a C2.5 class flare from AR 3234 at the time (N20W30). However, this faint event could also be back sided (no coronal signatures found for this).

Actual Shock Arrival Time: 2023-02-26T18:43Z

Observed Geomagnetic Storm Parameters:
----
CME Note: Partial halo CME seen mostly to the NW in SOHO LASCO and STEREO A COR2A coronagraphs. The CME is associated with an M3.7-class flare and subsequent eruption from AR3229. The flare induces a large nearby filament channel to break and lift off seen best in SDO/GOES 304, but also in SDO 193 and GOES-16 195. The flare and CME are also associated with a small enhancement in 10 MeV protons observed at GOES. The likely arrival of this CME (possibly a glancing blow) is first seen at 2023-02-26T18:43Z in DSCOVR data as a rapid increase in magnetic field from 10 nT to near 20 nT as well as a simultaneous increase in solar wind speed from 470 km/s to 540 km/s and density from 10 to 20 particles/cc.

Observed Geomagnetic Storm Parameters:
----
CME Note: CME seen in the NW of SOHO LASCO C2/C3 and STEREO A COR2. The CME is partially obscured by the pylon in SOHO LASCO C3. Potential source eruption starts around 2023-02-21T00:00Z and is a filament eruption characterized by movement/lift-off in SDO AIA 304, dimming in SDO AIA 193, post eruptive arcades in SDO AIA 171, and opening field lines in SDO AIA 171/193. Also visible in the NW of STEREO A EUVI 195. This CME may deflect towards the south in the field of view. Arrival signature discussed by Tarik Salman (LASSOS): Possible ICME encounter starting around 2023-02-24T12:08UT. This coincides with the start of a coherent period of field components and decreasing proton density. The total magnetic field is not significantly elevated over the background. The field components have constant profiles for extended periods which can be an indication of a possible glancing blow. This ICME is also observed to be expanding at L1. A possible end of this ICME is around 2023-02-25T07:26UT.

Actual Shock Arrival Time: 2023-02-20T09:52Z

Observed Geomagnetic Storm Parameters:
----
CME Note: Asymmetric halo CME associated with X2.2 flare from AR3229 (N25E65) at 17/1957UT, with an EUVI wave and with the eruption seen as dimming (as far east as -20 deg), best noticeable in STEREO A EUVI 195. The bright bulk of the CME seems to have gone in the more Eastern direction. The likely arrival of this CME is signified by a sharp increase in magnetic field to 14 nT, accompanied by a sudden jump in ion density to over 17 particles/cm^3 and of the solar wind speed from 370 to 430 km/s.

CME Note: Faint partial halo CME seen in SOHO LASCO C2/C3. Not visible in STEREO A COR2 due to a data gap from 2023-02-14T14:23Z to 2023-02-15T09:23Z. This eruption is associated with a C5.6 flare from AR 13220 and an eruption best seen in SDO AIA 304 starting around 2023-02-15T01:00Z centered around S05E15. The eruption can also be seen with dimming in SDO AIA 193. This CME leading edge is asymmetrical and has a component directed towards the south/southeast first visible in SOHO LASCO C2 at 2023-02-15T02:48Z while the rest of the CME starting at 02:12Z is directed more eastward. This eruption may be 2 simultaneous eruptions in close proximity but it is not clear if there are separate CMEs.

Actual Shock Arrival Time: 2023-02-13T17:02Z

Observed Geomagnetic Storm Parameters:
Max Kp: 5.33
CME Note: The CME visible N/NE in SOHO LASCO C2, C3 and STEREO A COR2 imagery. There is a more clear bulk portion that shows filamentary structures within it and then a more faint partial halo seen more clearly in difference imagery. The source is a filament eruption from the region NE of AR13216, there is also subsequent brightening, potential flaring from AR13216 during this eruption. From Tarik Salman, LASSOS team: Arrival is marked by the enhancement of the B field over the background, accompanied by a drop in proton density and the start of a low-density period. Temperature data seems to be sensitive. A significant data gap makes it difficult to analyze the nature of field rotations. However, the rotations might not be significant due to a possible flank crossing. Due to that, at L1, the flux rope is possibly not encountered.

CME: 2023-01-20T13:38:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: Bright, wide CME with filamentary structure seen to the southwest in SOHO LASCO and STEREO A COR2 coronagraphs. Associated with a large-scale filament eruption whose filament at 2023-01-20T11:00Z was stretched from S42W25 northwest to about S30W70 (center point approximately S35W52). The eruption and post eruptive brightening is seen best in SDO 304 but also in SDO 193/171/211 occurring near 13:00Z. Arrival observed at Earth on 2023-01-23T02:59Z is believed to be more likely associated with CME: 2023-01-20T16:12Z, though its arrival is possibly associated with this CME.

CME: 2023-01-19T11:36:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: Super faint CME (best seen in difference imagery) E in C2/C3 and COR2A. Its source is likely the relatively minor eruption associated with M class flare from AR 3196 (N12E38) peaking at 2023-01-19T10:12Z. Eruption is seen in AIA 304 starting around 2023-01-19T10:20Z and is directed mostly southward (explaining why the CME might be deflected to the south). Eruption is also seen in AIA 193 and EUVI A 195 as dimming (and possibly a EUV wave), with dimming mostly to the SE of the AR. Arrival observed at Earth on 2023-01-23T02:59Z is believed to be more likely associated with CME: 2023-01-20T16:12Z, but could be a combined arrival of two or more CMEs, including this one.

Observed Geomagnetic Storm Parameters:
----
CME Note: This CME is visible to the E/SE in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is an eruption and subsequent M6.0 flare from AR 3191 seen in SDO AIA 131, 171, 193, 304 imagery starting around 2023-01-15T03:20Z. Opening of field lines is visible off the eastern limb in SDO AIA 171 at this time, and post-eruptive dimming appears around 03:45Z in SDO AIA 193. Arrival is characterized by a sharp increase in magnetic field components with B total reaching 15 nT. Solar wind speeds increased from 387 km/s at 2023-01-17T20:53Z to 488 km/s at 2023-01-18T02:08Z. Additional increases in density and temperature. Signature is still developing and analysis is ongoing. This arrival may also be associated with CME: 2023-01-14T21:36Z.

CME Note: This CME is visible as a partial halo to the W/SW in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is an eruption and subsequent M4.6 flare from AR 3182 seen in SDO AIA 131, 171, 193, 304 imagery starting around 2023-01-14T20:35Z. An opening of field lines is visible in SDO AIA 171 at 20:50Z and post eruptive loops start to form in SDO AIA 193 around 22:30Z. Eruption is also visible in STEREO A EUVI 195 and 304 imagery. Arrival is characterized by a sharp increase in magnetic field components with B total reaching 15 nT. Solar wind speeds increased from 387 km/s at 2023-01-17T20:53Z to 488 km/s at 2023-01-18T02:08Z.

Actual Shock Arrival Time: 2023-01-14T21:50Z

Observed Geomagnetic Storm Parameters:
Max Kp: 5.0
CME Note: Faint CME with an interesting mushroom shape - or likely two or even three very close successive CMEs NNW in SOHO LASCO C2/C3 and STEREO A COR2. The source is likely a gradual eruption(s) in and NW of AR 3185 (N20W28) seen starting around 2023-01-12T01:00Z as seen in AIA 193 and EUVI A 195 with post-eruptive arcades near the AR and in the location NE of the AR. Arrival is likely associated with the interplanetary shock observed at L1 on 2023-01-14T21:50Z. This signature was characterized by an increase in Btotal to 11nT and solar wind speeds up to ~500 km/s. It was also accompanied by slight increases in density and temperature. Per advice from the LASSOS team, this arrival is likely a glancing blow due to the lack of a clear rotation in magnetic field components/flux rope signature.

CME: 2023-01-11T17:00:00-CME-001

This CME was not detected at Earth!

Observed Geomagnetic Storm Parameters:
----
CME Note: This is a large, bright and wide CME visible to the SE in SOHO LASCO C2/C3, and STEREO A COR2 imagery. The likely source is seen as clear moving/opening field lines beyond the SE limb in STEREO EUVI A 195 after 2023-01-11T16:35Z, followed by high rising post-eruptive arcades on the limb in EUVI A 195 an hour later. (Note: There also was an eruption in the SE on the Earth-facing disk seen in AIA 304 starting 2023-01-11T20:45Z (with a significant-area dimming south of the AR 3184(S13E41) seen in AIA 193) but this eruption was several hours later than the start of the CME and thus likely unrelated to it). CME was most likely backsided. This arrival is still being analyzed.

CME Note: This CME is seen to the NE in SOHO LASCO C2, C3, and STEREO A COR2 imagery. It overlaps the 2023-01-11T08:48Z CME. The source of this CME appears to be the M3.1 flare from AR13186. There is a simultaneous filament eruption seen beyond the NE limb that appears to be associated with the 2023-01-11T08:48Z CME. This CME was a candidate for the interplanetary shock observed at L1 on 2023-01-14T21:50Z, but per advice from the LASSOS team, it appeared the CME measured too fast to be responsible for the arrival signature (which did not have a dramatic increase in solar wind speeds).
