Note:

Best fit measurement using candidate source location, several SOHO LASCO C2 frames, and two frames of SOHO LASCO C3. The leading edge is narrow and for most frames is completely obstructed by the pylon in SOHO LASCO C3. This CME is completely covered by a data gap in STEREO A COR2 which lasted from 2025-02-16T11:38Z to 2025-02-16T15:23Z.
