CME Analysis Information (for CME activity ID: 2025-08-30T20:09:00-CME-001)
Measurement Creation Time: 2025-08-30T23:22Z
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:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Image Type: running difference
Speed (km/s): 1303.0
Speed measured at height (Rs): 20.5
Type: O
Direction (LON/LAT in HEEQ): -3.0/ 5.0
Half Angular Width (degree): 34.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-08-30T22:41Z
Info/Session URL: None Entered
Note: 
BULK measurement update. Triangulated measurement between SOHO LASCO C2/C3 and STEREO A COR2. Halo signature in LASCO C2/C3 is notably dimpled and non-circular, especially compared to STEREO A COR2. This analysis is the best fit of the bulk material excluding a southward nose that travels slightly faster than the main front.
