Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-12-14T22:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-12-14T22:00:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Northward CME with the possible source the faint opening field lines and ejecta seen beyond the northern limb in SDO AIA 171 starting at 2023-12-14T21:39Z. Filamentary material seen lifting off in SDO AIA 304 and GOES SUVI 304 starting at about 2023-12-14T21:32Z. Seems like it is at a high latitude, since we can see the full loop of the prominence on the north limb before it fully erupts.

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 |

Very approximate analysis since the high latitude source (filament eruption) is assumed to be behind the limb. Analysis is based on the fit in swpc_cat in 2 coronagraphs that is difficult to get for this imagery. |

This likely incorrect front-sided analysis is based on the source being a slowly developing filament eruption seen in AIA 304/194 as gradual dimming. However neither the latitude of the fit in swpc_cat no the filament timing fit with this perceived source: the CME appears in coronagraphs many hours later than the filament eruption starts and the fit requires a much higher latitude than the one of the dimming. |
