All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-10-17T08:12:00-CME-001 (version 1)
Source Location: N25W75
Active Region Number: 14246
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
O: Other
Note: CME seen to the NW in SOHO LASCO C2/C3 and GOES CCOR-1, and to the N in STEREO A COR2. Source is an eruption from AR 14246 (N25W75) seen as broadly opening field lines in GOES SUVI 284 starting at 2025-10-17T07:24Z, and a small amount of ejecta originating from AR 14246 (N25W75) seen in GOES SUVI 304 starting at 2025-10-17T07:37Z. Some brightening from AR 14246 is visible in STEREO A EUVI 304 imagery between frames 2025-10-17T07:15Z-08:15Z.
