CME Analysis Information (for CME activity ID: 2021-09-05T21:36:00-CME-001)
Measurement Creation Time: 2021-09-07T15:48Z
Catalog: M2M_CATALOG
Data Level: 1 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis)
Use as primary measurement: true
Measurement Technique: SWPC_CAT

Detecting Instruments:

SOHO: LASCO/C3

Image Type: running difference
Speed (km/s): 537.0
Speed measured at height (Rs): None Entered
Type: C
Direction (LON/LAT in HEEQ): 0.0/ 7.0
Half Angular Width (degree): 45.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2021-09-06T04:21Z
Info/Session URL: None Entered
Note:

Analysis of this CME was difficult due to the faint feature of the partial halo to the south of SOHO LASCO C2/C3 coronagraphs. The best fit for this CME led to speeds ranging from 450km/s to 550km/s. The best fit due to wide width was provided here and used to simulate this CME.
