Note: CME seen to the NE in SOHO LASCO C2/C3 and GOES CCOR-1, and due north in STEREO A COR2. Source is likely far-sided, with extremely high northern latitude field line movement seen in GOES SUVI 284 around 2025-11-24T19:06Z as well. It is difficult to tell whether this is on or just beyond the N limb but appears to be associated with continuous eruptions from a far-sided source present over the last few days. Triangulation attempting to match this to a filament eruption on the Earth-facing disk at nearly the same time around N40W10 to N50W10 failed.
