Image Type: running difference
Speed (km/s): 483.0
Speed measured at height (Rs): 15.3
Type: S
Direction (LON/LAT in HEEQ): -13.0/ -5.0
Half Angular Width (degree): 42.0
Minor Half-width (degree): None Entered

Time@21.5: 2026-03-16T18:59Z
Info/Session URL: None Entered
Note: 
Preliminary measurement following the brightest leading edge portions seen to the north and to the southeast. The measured parameters were based on the source location and best fit in SOHO LASCO C2 and GOES CCOR-1 imagery. Due to a data gap in STEREO A COR2 at the time of this event, a triangulated measurement was not available and the measured parameters may vary as a result.
