CME Analysis Information (for CME activity ID: 2025-04-28T15:48:00-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

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Image Type: running difference
Speed (km/s): 319.0
Speed measured at height (Rs): None Entered
Type: S
Direction (LON/LAT in HEEQ): -2.0/ 85.0
Half Angular Width (degree): 16.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-04-29T02:46Z
Info/Session URL: None Entered
Note:

Measurement based on triangulation between SOHO LASCO C2/C3 and STEREO A COR2. Due to the far northern latitude (~N85), there is a very wide range of possible longitudes. This is a very speculative longitude, and the CME could easily be farsided.
