Note: Plane-of-sky measurement using several frames of SOHO LASCO C2 and C3. Tricky to track the same leading edge between C2 and C3, since there are several slow loops that emerge in C2 and eventually merge into one brighter loop by the time C3's field of view is reached. There is also a data gap in STEREO A COR2 from 2025-02-21T15:53Z to 2025-02-22T03:23Z which completely covers this CME.
