Measurement Technique: SWPC_CAT

Detecting Instruments:

SOHO: LASCO/C2

SOHO: LASCO/C3

Image Type: running difference
Speed (km/s): 466.0
Speed measured at height (Rs): 7.1
Type: S
Direction (LON/LAT in HEEQ): -90.0/ -76.0
Half Angular Width (degree): 38.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-03-02T07:49Z
Info/Session URL: None Entered
Note:

Very preliminary measurement with limited frames in SOHO LASCO C2 and C3 imagery. No STEREO A COR2 available due to data gap. The CME exhibits a sheered-type of front with a portion moving faster than other portions. These parameters are based on following the faster portion of the CME with including the slower portion within the width of the measurement. The slower portion of this CME was measuring speeds closer to 200 km/s.
