Measurement Creation Time: 2021-12-21T13:16Z
Catalog: M2M_CATALOG
Data Level: 0 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis)
Use as primary measurement: false
Measurement Technique: SWPC_CAT

Detecting Instruments:

SOHO: LASCO/C2

Image Type: running difference
Speed (km/s): 357.0
Speed measured at height (Rs): 9.0
Type: S
Direction (LON/LAT in HEEQ): -13.0/ -1.0
Half Angular Width (degree): 31.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2021-12-20T14:31Z
Info/Session URL: None Entered
Note:

This measurement is using SOHO LASCO C2 in SWPC_CAT. The CME is faint in C2 and is not seen in either LASCO C3 or COR2A (Stereo imagery is available). The measurement is based off of the source location of the flare and associated eruption identified in SDO AIA imagery.
