Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-20T15:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-11-20T15:23:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Wide complex CME seen to the SW in STEREO A COR2 and to the SW in GOES CCOR-1. Not captured in real time by SOHO LASCO due to a scheduled data gap. Source is widely opening field lines beyond the STEREO A southwest limb seen starting as early as 2025-11-20T14:55 in STEREO A EUVI 195/304.
