Note: Faint CME first seen in the East by SOHO LASCO C2 beginning at 2025-04-15T23:36Z, as well as by SOHO LASCO C3 in later frames. This event is not visible in STEREO A COR2 due to a data gap beginning at 2025-04-15T18:53Z. There is no clear source seen on the disk for this event, aside from some general field line movement seen along the East limb in SDO AIA 171 and 193.
