CME Analysis Information (for CME activity ID: 2025-04-17T09:12:00-CME-001)
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:

SOHO: LASCO/C2

STEREO A: SECCHI/COR2

Image Type: running difference
Speed (km/s): 435.0
Speed measured at height (Rs): 11.0
Type: S
Direction (LON/LAT in HEEQ): -110.0/ 47.0
Half Angular Width (degree): 10.0

Info/Session URL: None Entered
Note:

Preliminary leading edge measurement using an isolated SOHO LASCO frame as well as STEREO A COR2 to triangulate the CME; the CME is likely faster than this measurement, but the longitude was largely obtained with this measurement.
