Note: CME first seen to the East by STEREO A COR2 beginning at 2026-03-08T18:08Z, as well as by GOES CCOR-1 in later frames. This CME is not visible in SOHO LASCO C2/C3 due to a data gap which began at 2026-03-08T16:12Z. The source of this event is a C2.0 flare and minor eruption seen in SDO AIA 131 and 304 peaking at 2026-03-08T15:07Z. This eruption was followed by a small dimming signature seen located at approx. N05E60 beginning at approx. 2026-03-08T17:04Z as seen in GOES SUVI 195.
