Speed measured at height (Rs): 8.9
Type: C
Direction (LON/LAT in HEEQ): 25.0/ 51.0
Half Angular Width (degree): 19.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-03-05T17:54Z
Info/Session URL: None Entered
Note:

Triangulated measurement using mostly SOHO LASCO C2/C3 frames, with two STEREO COR2A frames helping triangulate the longitude prior to its data gap beginning at 2025-03-05T11:53Z. This CME front diffuses out after an initial solid view in LASCO C2, it was much easier to track the leading edge in the earliest frames used for this measurement.
