Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2021-01-01T22:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2021-01-01T22:00:00-CME-001 (version 2)
Note Keyword:
HAL: Halo CME

FIL: Filament eruption
Morphology Keyword:
Note: Source is a large filament eruption seen just south of center starting around 20:00Z. CME is seen as a partial halo in C2/C3 images.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME

CME Analysis M2M_CATALOG true StereoCAT 15.0 -22.0 372.0 S 25.0 2021-01-02T07:27Z This CME analysis used STEREO A COR2 science data to measure the plane-of-sky speed. Using the visible source signature in SDO and possible CME fits in SWPC_CAT, a longitude was approximated and triangulation yielded the above 3D parameters. This measurement accounts for a more southward latitude based on the source signature. 1: Result 1 (2.0 AU)
Earth = 2021-01-05T20:30Z (PE: 8.2 h)

CME Analysis M2M_CATALOG false SWPC_CAT 14.0 -10.0 544.0 C 10.0 2021-01-02T02:35Z Rough measurement only using early C2 images. Lat/long picked based on early difference images as being fairly center-disk, but the filament eruption was wide and later, more diffuse frames compared to the SDO images of the eruption suggest that most of the material flowed in a more western direction. 1: Result 1 (2.0 AU)
Earth = 2021-01-05T20:00Z (PE: 7.7 h)
2: Result 2 (2.0 AU)
Earth = 2021-01-05T14:00Z (PE: 1.7 h)

CME Analysis M2M_CATALOG false StereoCAT 44.0 -19.0 330.0 S 48.0 2021-01-02T11:20Z The CME was remeasured after C2/C3 images became available, and it was clear that the CME has a partial halo component (originally only difference images were available). CME was not clearly visible in the difference images, so STEREO_CAT was used. 1: Result 1 (2.0 AU)
Earth = 2021-01-05T15:15Z (PE: 2.9 h)
