Coronal mass ejection — 2026-10-10 08:36 UTC
CME observed to the NW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is former AR 14547 (~N15W105) as directly observed by STEREO A around the west limb from SDO. Observed across SDO AIA 131/171/193/211/304 as field line movement and EUV wave, and brightening, starting around 2026-10-10T07:51Z, partially obscured by a rare transit of the moon across the SDO AIA field-of-view. Also seen in STEREO A EUVI 195/304 as brightening, dimming, and field line movement starting around 2026-10-10T07:55Z.
