All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-01-17T03:00:00-CME-001 (version 1)
Source Location: S09W88
Active Region Number: 14336
Note Keyword:
Faint: Faint event; may affect type assignment
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
Morphology Keyword:
J: Jet
Note: Jet-like CME visible to the W in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source appears to be a C4.7 flare from AR 14336 just on/beyond the western limb in SDO/AIA 304 starting around 2026-01-17T02:22Z. The filament eruption is also visible in STEREO A EUVI 304 with possible deflection to the W due to a nearby coronal hole.
