Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-03T05:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-10-03T05:53:00-CME-001 (version 1)
Source Location: N14W12
Active Region Number: 14236
Note Keyword:
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
Morphology Keyword:
Note: This CME is visible to the east in STEREO A COR2, SOHO LASCO C2/C3, and faintly in GOES CCOR-1 coronagraph imagery. The source is likely related to an M1.5 flare from Active Region 14236 (N14W12) starting around 2025-10-03T05:00Z as seen in GOES SUVI 131, 171, 195, 284, 304 and STEREO A EUVI 195 and 304 imagery. Post eruptive arcades are visible starting around 2025-10-03T06:00Z as seen in GOES SUVI 171 and 195 imagery.
