CME Analysis Information (for CME activity ID: 2026-01-31T19:23:00-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: false
Measurement Technique: SWPC_CAT

Detecting Instruments:

SOHO: LASCO/C2

SOHO: LASCO/C3

Image Type: running difference
Speed (km/s): 576.0
Speed measured at height (Rs): None Entered
Type: C
Direction (LON/LAT in HEEQ): 142.0/ 4.0
Half Angular Width (degree): 17.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2026-02-01T02:59Z
Info/Session URL: None Entered
Note:

3D single spacecraft analysis with SOHO LASCO C3 and one LASCO C2 frame, using the observed source around W141.8 in STEREO A EUVI imagery as the basis, and the longitude could easily  vary +-10 degrees. Analysis is quite speculative due to LASCO data quality with an ongoing campaign, STEREO A COR2 data gap, and LASCO C2/C3 and GOES CCOR-1 fronts not aligning well with the lemniscate tool.
