Activity ID: 2025-10-15T23:15:00-CME-001 (version 2)
Source Location: N25W55
Active Region Number: 14246
Note Keyword:
3P: 3-part structure CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming

Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: CME visible to the NW in GOES CCOR-1 and SOHO LASCO C2/C3. Visible to the north in STEREO A COR2. The source is an M2.7 flare peaking at 2025-10-15T22:28Z from Active Region 14246 (N25W55). An eruption with dimming, EUV wave, opening field lines, and post-eruption arcades is best seen in GOES SUVI 195 and from the point of view of STEREO A EUV 195.
