Note: CME first seen to the SW in SOHO LASCO C2 stating at 2026-06-13T13:26Z. It is also seen to the SW in SOHO LASCO C3 and GOES CCOR-1 and to the S in STEREO A COR2. The majority of this CME was missed by SOHO LASCO C2/C3 in real time due to a data gap between downlink periods. The source of this CME is a large eruption in across the far SE portion of the Earth-facing disk centered around AR 14461 (S21W68). The eruption is best seen in SDO AIA 193 as wide opening field lines accompanied by dimming and an EUVI wave beginning around 2026-06-13T12:36Z. This CME is also associated with a C2.5 class flare from AR 14461 which peaked at 2026-06-13T13:09Z. The flare is best seen in SDO AIA 131.
