Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-15T18:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-05-15T18:00:00-CME-001 (version 1)
Source Location: N17E47
Active Region Number: 14087
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
Morphology Keyword:
Note: Faint CME visible to the NE in SOHO LASCO C2. It is unclear if this CME is also visible in STEREO A COR2 due to data quality as well as GOES CCOR-1 due to obstruction from the control arm. The source appears to be an M2.1 flare from AR 14087 with associated filament ejecta best seen in SDO/AIA 304 and 131.
