CME Analysis Information (for CME activity ID: 2025-09-25T19:12:00-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:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Image Type: running difference
Speed (km/s): 534.0
Speed measured at height (Rs): 9.0
Type: C
Direction (LON/LAT in HEEQ): 25.0/ -46.0
Half Angular Width (degree): 25.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-09-26T02:00Z
Info/Session URL: None Entered
Note:

Best fit measurement using source location seen in UV imagery with some southeastward deflection, several frames of SOHO LASCO C2, one frame of SOHO LASCO C3, and one frame of STEREO A COR2. Leading edge becomes too diffuse to track a few frames into the SOHO LASCO C3 field of view.
