CME Analysis Information (for CME activity ID: 2021-11-02T02:48:00-CME-001)
Measurement Creation Time: 2021-11-02T18:19Z
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

STEREO A: SECCHI/COR2

Image Type: running difference
Speed (km/s): 1151.0
Speed measured at height (Rs): 23.0
Type: O
Direction (LON/LAT in HEEQ): -5.0/ 16.0
Half Angular Width (degree): 51.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2021-11-02T05:52Z
Info/Session URL: None Entered
Note:

This SWPC_CAT measurement approximated a match between the CME's leading-edge visible to the SE in SOHO LASCO C3 and to the SW in STEREO A COR2. Imagery from STEREO A COR2 was used to estimate an appropriate half-width and suggested a slight deflection to the east (based on the emergence of an asymmetric halo visible in later frames).
