Coronal mass ejection — 2026-10-12 19:36 UTC
Narrow CME first seen to the SW by SOHO LASCO C2 beginning at 2026-10-12T19:36Z, as well as by GOES CCOR-1 in later frames. This CME is not visible in STEREO A COR2 due to a data gap which began at 2026-10-12T18:58Z. The source of this event is rising field line loops seen originating from beyond the SW limb in SDO AIA 171 beginning at approx. 2026-10-12T18:18Z.
