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: true
Measurement Technique: SWPC_CAT

Detecting Instruments:

STEREO A: SECCHI/COR2

GOES: CCOR-1

Image Type: running difference
Speed (km/s): 661.0
Speed measured at height (Rs): 14.0
Type: C
Direction (LON/LAT in HEEQ): 53.0/ 16.0
Half Angular Width (degree): 22.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2026-05-20T21:58Z
Info/Session URL: None Entered
Note:

The CME was reanalyzed with later imagery and with inclusion of the more southern lobe of the CME in addition to its northern lobe. Analysis is based on the fit of the faint front in two coronagraphs (GOES CCOR-1 and STEREO A COR2) and takes into account the location of the erupting filament. LASCO imagery is absent at the time of analysis.
