CME Analysis Information (for CME activity ID: 2025-08-28T20:12:00-CME-001)
Measurement Creation Time: 2025-08-29T01:22Z
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): 1104.0
Speed measured at height (Rs): 17.0
Type: O
Direction (LON/LAT in HEEQ): -85.0/ 25.0
Half Angular Width (degree): 19.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-08-28T23:30Z
Info/Session URL: None Entered
Note:

Best fit measurement using several frames of GOES CCOR-1 and a few frames of STEREO A COR2. The leading edge is extremely diffuse, adding some uncertainty to this measurement. This CME was captured by only one frame of SOHO LASCO C2 in real time, due to a regularly scheduled downlink data gap which began 2025-08-28T20:24Z.
