Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-22T17:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2025-04-22T17:24:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
Morphology Keyword:
L: Loop
Note: Faint, puff-like loop CME seen to the north in SOHO LASCO C2 and to the northwest and widening with time as the CME propagates, the CME is with high confidence likely originating from the far-side as suggested by this geometry and there are no sources on the Earth-facing disk to suggest this CME originates from the Earth-facing solar disk.
