Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-09T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2025-11-09T21:12:00-CME-001 (version 2)
Note Keyword:
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
Morphology Keyword:
Note: This CME is faint but visible to the east in SOHO LASCO C2 imagery and to the southwest in STEREO A COR2 imagery for a few frames before becoming too diffuse to observe. The CME is not visible in GOES CCOR-1. The source is likely far-sided as there are no signatures on the Earth-facing disk around the time of this event.
