Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-26T15:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3

Activity ID: 2025-02-26T15:00:00-CME-001 (version 1)
Source Location: S30W70
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
Note: Bright CME first seen to the SW in SOHO LASCO C2, C3, and after a data gap in STEREO A COR2 imagery. The source of this CME is a filament eruption seen near S30W70 in SDO/AIA, STEREO A EUVI and GOES SUVI 304 starting around 2025-02-26T14:00Z. There is strong southern deflection of the eruption, likely due to the large coronal holes to the north and east of the source location. Field line opening is also visible in SDO/AIA 171, 193, and 211.
