Coronal mass ejection — 2026-10-19 14:48 UTC
CME first seen to the NNW in SOHO LASCO C2 starting at 2026-10-19T14:48Z. This CME is also seen to the NNW in SOHO LASCO C3 and GOES CCOR-1 and to the NW in STEREO A COR2. The source of this CME is an eruption beyond the NW limb seen as moving field lines beyond the NW limb in STEREO A EUVI 195 beginning around 2026-10-19T11:05Z. The eruption likely occurred in proximity to a large coronal hole that is approaching the western limb from the perspective of STEREO A. Some deflection is likely.
