Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-17T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-10-17T21:12:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
FIL: Filament eruption
BR: Brightening
Morphology Keyword:
L: Loop
Note: CME seen to the WNW in SOHO LASCO C2/C3 and GOES CCOR-1. Not captured by STEREO A COR2 due to a data gap lasting from 2025-10-17T18:23Z to 2025-10-18T00:08Z. Source is likely a filament eruption just beyond the West limb, as seen in GOES SUVI 304 starting around 2025-10-17T20:25Z. Post-eruptive brightening can also be seen around N10W105 in STEREO A EUVI 304 after a data gap which ended at 2025-10-18T00:15Z.
