Measurement Creation Time: 2025-08-28T02:45Z
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): 617.0
Speed measured at height (Rs): 14.0
Type: C
Direction (LON/LAT in HEEQ): -15.0/ 26.0
Half Angular Width (degree): 15.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-08-28T01:50Z
Info/Session URL: None Entered
Note:

Best fit measurement using several frames of STEREO A COR2 and GOES CCOR-1. Leading edge is extremely faint in GOES CCOR-1, adding some uncertainty to the measurement. Not captured in real time by SOHO LASCO due to a data gap which began 2025-08-27T12:30Z.
