Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-08T05:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-05-08T05:36:00-CME-001 (version 2)
Source Location: S22W10
Active Region Number: 13664
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
DPL: CME exhibits dimpled front
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
DFLR: Double ribbon flare
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Earth-directed full halo seen in all coronagraphs. The source is a large eruption from AR 3664, which included two flares seen in SDO AIA 131, an initial M3.5 (S21W10) followed by the main long-duration X1.0 (S22W10) which peaked at 2024-05-08T04:30Z and 2024-05-08T05:09Z respectively. An EUV wave and field line movement is observed in SDO AIA 94/131/171/211 with some surface brightening in SDO AIA 304. This flare+CME combo resulted in a small rise in protons observed at SOHO and GOES, but not enough for a threshold crossing.

CME Analysis M2M_CATALOG LE true SWPC_CAT 9.0 -7.0 870.0 C 43.0 2024-05-08T09:30Z BULK measurement using both coronagraphs to triangulate the same features, using AR 3664 as the source. This CME front is notably asymmetric in all imagery, but there is high confidence in all three "nodes" in different directions pertaining to the same CME front directed towards Earth from this same eruption. The right hand boundary was mainly used, matching the half-width to the peaks of each node of the asymmetric front, which tracked surprisingly well once aligned. 1: Result 1 (2.0 AU)

Source of AR 3664 (S22W10) used as a basis finding a good triangulation between coronagraphs near here, mainly tracking the southern portion of the front as it is the most visible and distinguishable amongst the rest of the complex running difference imagery at this time. 1: Result 1 (2.0 AU)
