All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-01-17T07:00:00-CME-001 (version 2)
Note Keyword:
DFL: Likely deflection of the event within the FOV
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
PEA: Post eruption arcade

Note: This CME is visible to the SW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is a filament eruption visible in all SDO/AIA wavelengths, in GOES SUVI wavelengths (including 304 and 284), and in STEREO A EUVI 304 and 195 starting around 2026-01-17T04:45Z.
