Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-12-20T23:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-12-20T23:48:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
U: Unknown
Note: Narrow CME visible to the SW in SOHO LASCO C2/C3 and STEREO A COR2, directly following CME: 2024-12-21T21:12Z in the field of view of the coronagraphs. The potential source is near or beyond the west limb as seen in SDO AIA and STEREO A EUV imagery. In GOES SUVI 304, ejecta can be seen departing on the limb starting at 2024-12-20T23:00Z. Moving/opening field lines are also visible in GOES SUVI 195/284 and STEREO A EUV 195.
