CME Analysis Information (for CME activity ID: 2024-12-28T02:48:00-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): 727.0
Speed measured at height (Rs): 11.4
Type: C
Direction (LON/LAT in HEEQ): 95.0/ -51.0
Half Angular Width (degree): 10.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2024-12-28T07:44Z
Info/Session URL: None Entered
Note:

Triangulated measurement between SOHO LASCO C2/C3 and STEREO COR2A, noting the CME deflecting southward from the source based on how it travels through the coronagraphs, complicating swpc_cat's tracking of the front direction. However, this fit is close to the estimated source as observed in STEREO EUVI imagery, with visual triangulating getting worse if you go further beyond W95.
