Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-21T07:23Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-02-21T07:23:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
L: Loop
Note: Fairly slow CME seen to the southwest in SOHO LASCO C2 and farther south in STEREO A COR2A; the source is possibly associated with a filament eruption seen in SDO AIA 304 occurring on the Earth-facing disk around 2025-02-21T06:30Z, however, the CME appears to fit to a longitude of W30 to W50 which is not associated with any eruptions visible on the Earth-facing disk.
