Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-15T00:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-12-15T00:00:00-CME-001 (version 2)
Source Location: S35W80
Note Keyword:
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
Morphology Keyword:
Note: Loop CME seen to the southwest in SOHO LASCO C2/C3 and GOES CCOR-1. Not seen in STEREO A COR2 due to a data gap. Associated with a major prominence eruption taking place near 2025-12-15T00:00Z as seen best in GOES SUVI 304, with one footpoint behind the western limb and another near S35W75. Bright post eruptive activity is visible near the centerpoint following the filament liftoff in GOES SUVI 304.
