Coronal mass ejection — 2026-10-19 19:15 UTC
Faint CME observed to the NW in GOES CCOR-1. It may be visible to the NW in STEREO A COR2, but only one available frame of imagery does not clearly show the CME. No real-time visibility in SOHO LASCO C2/C3 due to a data gap starting around 2026-10-19T18:48Z. The source is likely far-sided from Earth, observed around N10W130 as brightening in STEREO A EUVI 304 at 2026-10-19T18:15Z, and EUVI 195 at 2026-10-19T18:25Z. Also observed over the NW limb in GOES SUVI 284 as faint field line movement.
