Note: CME seen to the southeast in GOES CCOR-1 and STEREO A COR2 but not in SOHO LASCO due to a data gap; the CME is probably associated with destabilizing magnetic loop with bright post eruptive arcades near AR 4334 (S17E43) seen best in SDO AIA 171 around 2026-01-05T08:20Z seen through 2026-01-05T09:30Z.
