Note: CME seen to the NE in GOES CCOR-1 and SOHO LASCO C2/C3. The CME is not visible in STEREO A COR2 in real-time due to a data gap starting at 2026-03-24T13:53Z. The source is a C7.2 flare starting at 2026-03-24T17:18Z as seen in GOES SUVI 131 imagery. Opening field lines and post-eruptive arcades are also visible near the NE limb in GOES SUVI 171/195/284/304 imagery.
