Note: This CME is visible to the E in GOES CCOR-1 and to the NE in STEREO A COR2 imagery. There is a real-time data gap for SOHO LASCO C2/C3 currently. This CME is associated with the M8.1 flare from Active Region 14513 (N05E80) peaking at 2026-08-20T11:42Z as seen in SDO/AIA 131, 193, 171, and 304. Associated moving/opening field lines are visible to the E/NE in SDO/AIA 193 and 171, as well as filament material in SDO/AIA 304. These features are additionally visible in GOES SUVI wavelengths.
