Image Type: running difference
Speed (km/s): 406.0
Speed measured at height (Rs): None Entered
Type: S
Direction (LON/LAT in HEEQ): -139.0/ -9.0
Half Angular Width (degree): 37.0

Tilt (degree): None Entered
Time@21.5: 2026-03-07T10:50Z
Info/Session URL: None Entered
Note:

Very speculative, approximate analysis with two coronagraphs, initially based on the fitting of the clear halo front in STEREO A COR2A and later assuming that one of the less clear follow up fronts in SOHO/CCOR1 is the corresponding front (likely the front first seen in SOHO LASCO C2 at 2026-03-07T00Z), however this front is more of a speculation. The speeds in analysis can vary depending on the chosen half width, which in this analysis was based on the SOHO LASCO imagery and set to 37 degrees.
