Image Type: running difference
Speed (km/s): 1441.0
Speed measured at height (Rs): 7.0
Type: O
Direction (LON/LAT in HEEQ): 100.0/ 6.0
Half Angular Width (degree): 46.0
Minor Half-width (degree): None Entered

Time@21.5: 2023-07-15T22:38Z
Info/Session URL: None Entered
Note:

Measurement made using best fit between SOHO LASCO C2 and STEREO A COR2. Difficult to get a good measurement for this CME due to the changing shape of the bulk and limited imagery from the coronagraphs (CME moves quickly thru C2, not visible to measure in C3 difference imagery, data gap in COR2A limits measurement to three frames where CME is in the FOV).
