Note: Outflow-like CME seen to the west in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 likely associated with far-sided eruptive activity suggested by the geometry of the CME as observed from STEREO A. May be associated with some rising field lines observed behind the northwest limb as seen in SDO AIA 171 around 2026-01-04T04:00Z.
