Note: Faint CME first seen to the North by SOHO LASCO C2 beginning at 2026-03-02T01:26Z, as well by SOHO LASCO C3 and STEREO A COR2 in later frames. This CME is not visible in GOES CCOR-1 due to a brief eclipse period. The source of this event is likely far sided, but field line opening can be seen along the NE limb in GOES SUVI 195 beginning at approx. 2026-03-01T23:48Z.
