CME Analysis Information (for CME activity ID: 2025-05-20T20:00:00-CME-001)
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

Image Type: running difference
Speed (km/s): 1043.0
Speed measured at height (Rs): None Entered
Type: O
Direction (LON/LAT in HEEQ): -55.0/ -51.0
Half Angular Width (degree): 14.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-05-20T23:25Z
Info/Session URL: None Entered
Note:

Single spacecraft 3D measurement with SOHO LASCO C2 only. STEREO A COR2 not available due to a data gap, and the LASCO C3 pylon greatly obscures the CME front in white light and running difference imagery. As such, the latitude and longitude may vary +- 10 degrees in either direction, with good confidence in the southern deflection from the observed source via SDO AIA and GOES SUVI imagery.
