Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-11-21T18:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-11-21T18:12:00-CME-001 (version 3)
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
HAL: Halo CME
SEP: Solar Energetic Particle event
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Bright and fast partial halo to the northwest, with bulk and (fainter) shock fronts, associated with the fast backsided eruption marked by an EUV wave and fast opening of field lines behind the NW limb seen around 2024-11-21T18Z. The source is backsided, based on the coronal signatures and might be Active Region 3889 which would be at the longitude 115 to 120 degrees at the moment.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

Very uncertain analysis based on the fit with ONE coronagraph only (SOHO) since there is no imagery from STEREO A COR2 because of an extensive data gap and the source is backsided, based on the coronal signatures. The range of possible longitudes that produce a decent fit in SOHO is from 115 to 140 degrees. |
1: Result 1 (2.0 AU)
2: Result 2 (5.5 AU)

Preliminary analysis based on the SHOCK of the CME. Higher degree of uncertainty with parameters due to single-spacecraft analysis. |
