Note: 
Plane-of-sky measurement of the faint leading edge using several frames of SOHO LASCO C2 and two frames of SOHO LASCO C3. Unable to be tracked farther than two frames in SOHO LASCO C3, due to the C3 running difference imagery being heavily affected and/or corrupt beginning at timestamp 2025-04-09T22:40Z. No STEREO A COR2 imagery was available in real time for this CME due to a data gap which began at 2025-04-09T18:53Z.
