Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-09-23T09:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-09-23T09:12:00-CME-001 (version 3)
Source Location: N50W20
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
U: Unknown
Note: Faint CME seen to the NE in SOHO LASCO C2/C3 and STEREO A COR2. The potential source is a filament eruption seen lifting off starting around 2024-09-23T07:17Z in SDO AIA 304 centered around N50W20. Dimming is also visible in SDO AIA 193. The eruption is also visible from the point of view of STEREO A EUV 195. While the filament does not clearly deflect in EUV imagery, this is the most likely candidate source for this CME based on event timing and location.
