| Soho Lasco Note | Faint, narrow CME first seen to the SW in SOHO LASCO C2 beginning at 2026-03-13T18:12Z, as well as by SOHO LASCO C3 and partially in GOES CCOR-1, as this CME is partially obscured by the pylon. This CME is not visible in STEREO A COR2 due to a data gap which began at 2026-03-13T15:09Z. There is no c |
