CME Analysis Information (for CME activity ID: 2025-10-23T16:38:00-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

STEREO A: SECCHI/COR2

Image Type: running difference
Speed (km/s): 465.0
Speed measured at height (Rs): 9.2
Type: S
Direction (LON/LAT in HEEQ): 10.0/ -5.0
Half Angular Width (degree): 30.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-10-23T23:41Z
Info/Session URL: None Entered
Note:

This measurement is speculative as this event is difficult to observe in SOHO LASCO C2 imagery due to the faintness and overlapping material from preceding events. However, this measurement is based on the approximate source location and best fit between STEREO A COR2 and SOHO LASCO C2 imagery.
