CME Analysis Information (for CME activity ID: 2021-10-28T15:53:00-CME-001)
Measurement Creation Time: 2022-09-22T00:55Z

Image Type: running difference
Speed (km/s): 1109.0
Speed measured at height (Rs): None Entered
Type: O
Direction (LON/LAT in HEEQ): 0.0/ -17.0
Half Angular Width (degree): 49.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2021-10-28T18:52Z
Info/Session URL: None Entered
Note:

Initial analysis with 6 early frames (including 1 starting frame in SOHO LASCO C3). The longitude of 0 deg. is based mostly on the appearance of CME as a symmetrical (southern) halo in SOHO LASCO C2. The fitting in SWPC CAT indicated higher latitude than the lat of the source (AR 2887 at S26W04) and of associated flare. Fitting suggested a higher half-width than the default 45 deg. and 49 deg produced a decent fit.
