Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-20T09:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-20T09:24:00-CME-001 (version 1)
Note Keyword:
COL: Possible collision with previous CME
FF: Event fails/disappears before exiting COR2
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the SE in SOHO LASCO C2 starting at 2025-04-20T09:24Z. Also seen to the SE in SOHO LASCO C3 and STEREO A COR2. This CME overtakes a slower loop originating from close to the same source with a start time of 2025-04-20T08:48Z. The source of this CME is likely a rising loop of plasma seen on/near the SE limb for a few hours prior to the CME start time.
