Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-09T18:45Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
STEREO A: SECCHI/COR2
Activity ID: 2025-12-09T18:45:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is visible to the SW in GOES CCOR-1 and STEREO A COR2. The CME is not visible in SOHO LASCO C2/C3 due to a data gap starting at 2025-12-09T11:00Z. The source appears to be a filament eruption from beyond the western limb in GOES SUVI 304 starting around 2025-19-09T18:04Z. Moving/opening field lines along the W/SW limb in GOES SUVI 284 starting around 2025-12-09T16:00Z.
