Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2022-01-21T09:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2022-01-21T09:53:00-CME-001 (version 3)
Source Location: S20E60
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
Note: This CME is associated with a filament/prominence eruption visible toward the SE limb of the Earth-facing disk in SDO AIA 193/304 near S20E60 (near AR 2934) starting around 2022-01-21T07:45Z. A corresponding dimming/ejection of material is visible to the SE in STEREO A EUVI 195 starting around the same time. The CME appears as a partial halo in STEREO A COR2.

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 |
