Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-08-30T22:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-08-30T22:12:00-CME-001 (version 2)
Source Location: N15W15
Note Keyword:
DFL: Likely deflection of the event within the FOV
DPL: CME exhibits dimpled front
GAP: Data gap
HAL: Halo CME
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
FIL: Filament eruption
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Partial halo seen in SOHO with clear fronts in the S and in the NE. Its source could be the eruption of a long NE-SW-stretched filament starting 2023-08-30T20:30Z - a long filament centered around N15W15 as seen in AIA 193/304; there is also a more minor dimming near the disk center after the initial filament eruption above.

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 approximate swpc_cat-fit-based analysis because of the non-circular shape of the CME; leaning towards negative longitude based on the observation that the bulk of the CME seemingly went more towards the SE as seen in coronagraph. Using default half width since this is a halo CME. |

Preliminary measurement of fainter shock front, based on the assumption that this is a front-sided event and on a fit of S and NE fronts in swpc_cat with the default half width. It looks like the CME got deflected from the source filament eruption NW of disk center, but then there is also lighter darkening near disk center. |
