Note: CME first seen to the West by SOHO LASCO C2 beginning at 2025-11-04T11:00Z, as well as by SOHO LASCO C3 in later frames. Not clearly seen in GOES CCOR-1. The source of this event is a minor eruption and field line opened seen along the Western limb in GOES SUVI/STEREO A EUVI 195 and 304 beginning at approx. 2025-11-04T10:06Z. A C4.6 flare from AR 14267 (N01W85) is also visible in association with this event.
