Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-19T07:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-19T07:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: CME faintly visible to the SE in SOHO LASCO C2/C3 and STEREO A COR2. The CME is partially obscured by the pylon in SOHO LASCO C3. The source is likely farsided, and opening field lines can be best seen beyond the SE limb starting at 2025-04-19T06:14Z in SDO AIA 193 and in SDO AIA 171 in ISWA. The eruption is not clearly visible in STEREO A EUV imagery.
