Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-31T20:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-10-31T20:24:00-CME-001 (version 2)
Source Location: N27E90
Note Keyword:
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: CME seen to the NE in all coronagraphs (SOHO LASCO C2/C3, STEREO A COR2 and GOES CCOR-1). Its source is the occulted C7.1 flare from what is possibly the former AR 14246 currently just behind the NE limb, with the flare peeking from behind the limb at ~N27E90, and an associated eruption with wide opening of field lines/restructuring of mag. field after 2025-10-31T19:40Z in the NE, seen in GOES SUVI 284/195/304. This event is also associated with type II radio burst.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.
