Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-10-09T16:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-10-09T16:12:00-CME-001 (version 1)
Source Location: S00W90
Active Region Number: 13842
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: CME visible to the W/NW in SOHO LASCO C2, C3, and a few frames of STEREO A COR2 after a data gap in STEREO A COR2 lasting from 2024-10-09T13:53Z to 2024-10-09T18:53Z. This CME is associated with the X1.4 flare from AR 13842 (S10W85) close to the SW limb. There is a narrow stream of ejecta visible in GOES SUVI 304 sourced from AR 13842 but deflected to the north and off the limb. In GOES SUVI 284, wide and fast opening field lines and departure of plasma from the W limb is visible. Very limited SDO AIA imagery for this event due to a shutter maneuver.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

Measurement using approximate longitude of source location observed in UV imagery along with the best fit in available frames of SOHO LASCO C2 and C3 imagery. The leading edge of this CME was not captured by COR2A due to a data gap. |
1: Result 1 (2.0 AU)
2: Result 2 (5.5 AU)

Plane of sky measurement using SOHO LASCO C2 and C3 frames. SOHO LASCO image quality heavily affected by the comet observations/campaign. The leading edge of this CME was already beyond the COR2A field of view after a data gap in STEREO A COR2 lasting from 2024-10-09T13:53Z to 2024-10-09T18:53Z. |
