Note: CME first seen to the East in STEREO A COR2 beginning at 2025-08-26T14:09Z, as well as by SOHO LASCO C2/C3 and GOES CCOR-1 in later frames. The source of this event is a small eruption centered at approx. S17E70 beginning at approx. 2025-08-26T12:55Z. Opening field lines can be seen in SDO AIA 171 and 193, along with post eruptive arcades visible in SDO AIA 94.
