Image Type: running difference
Speed (km/s): 751.0
Speed measured at height (Rs): None Entered
Type: C
Direction (LON/LAT in HEEQ): 122.0/ 15.0

Time@21.5: 2023-05-13T04:55Z
Info/Session URL: None Entered
Note:

Measurement of what appears to be the shock front of the CME, based not on the longitude of the source (C9 class flare) but on the best fit in SOHO and STEREO A coronagraphs. Yields much higher longitude (122 deg) than the longitude of the source (~76 deg).
