Coronal mass ejection — 2026-10-07 13:53 UTC
CME first seen to the NE in STEREO A COR2 starting at 2026-10-07T13:53Z. So far it is only visible in COR2A. The source of this CME is a C7.9 class flare from AR 14549 (N10W04) peaking at 2026-10-07T13:17Z best seen in SDO AIA 171. Some dimming and an EUVI wave associated with the eruption can be seen in SDO AIA 193. Some deflection is evident in the measurement of this CME, likely due to it close proximity to a coronal hole to the SE of AR 14549.
