Note: CME first seen to the SW in SOHO LASCO C2. Also seen to the SW in SOHO LASCO C3 (very faint in white light imagery) and STEREO A COR2. This CME is overtaken by the faster CME: 2025-04-12T10:48Z. The source of this CME is likely far-sided as there are not any good source candidates on the Earth-facing disk. There is some very faint field line movement from beyond the WSW limb best visible in GOES SUVI 284 that could be related. A far-sided source is supported by triangulation from SWPC_CAT measurement.
