Direction (LON/LAT in HEEQ): None Entered / -45.0
Half Angular Width (degree): 36.0

Time@21.5: 2023-12-28T07:01Z
Info/Session URL: None Entered
Note:

Definitive 3D analysis not possible since no coronal signatures have been found and swpc_tool gives good fits with longitudes from 90 to 150 degrees with two coronagraphs. This analysis focuses on the narrower brighter feature, likely the bulk of the CME. A wider fainter front extending southward could indicate a shock or a more faint feature of the CME and was excluded from this analysis.
