Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-01T21:00Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-12-01T21:00:00-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:
Morphology Keyword:
F: Flux Rope
Note: A minor CME to the ESE in GOES CCOR-1, SOHO LASCO C3 and STEREO A COR2, following in the footsteps of CME: 2025-12-01T15:08Z. The start might be earlier, as it is covered by a data gap in SOHO LASCO. No clear source has been found for this CME on the solar disk, however a possible culprit is Active Region 14294 that has minor activity today.
