CME Analysis Information (for CME activity ID: 2026-05-20T17:15:00-CME-001)
Measurement Creation Time:
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:

STEREO A: SECCHI/COR2

GOES: CCOR-1

Image Type: running difference
Speed (km/s): 574.0
Speed measured at height (Rs): 13.0
Type: C
Direction (LON/LAT in HEEQ): 48.0/ 20.0
Half Angular Width (degree): 18.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2026-05-20T22:30Z
Info/Session URL: None Entered
Note:

Very approximate analysis based on the fit of the larger lobe of this CME in early imagery in two coronagraphs, GOES CCOR-1 and STEREO A COR2, and roughly corresponding to the source eruption's parameters. The front of the CME is faint and somewhat unclear in both coronagraphs.
