Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-21T10:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-21T10:12:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
Note: CME first seen to the W in SOHO LASCO C2 starting at 2025-04-21T10:12Z. Also visible to the W in SOHO LASCO C3 and for a few frames in STEREO A COR2. The source of this CME is most likely an eruption near the WNW limb starting around 2025-04-21T08:45Z. It is seen across all SDO AIA wavelengths; however, it is best seen as some brightening and field line movement on the WNW limb in SDO AIA 193.
