Activity ID: 2023-07-31T23:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment

FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Faint CME seen as a partial halo to the SW in SOHO LASCO C2, C3, and STEREO A COR2 imagery. This feature overlaps multiple CME fronts to the SW. The source appears to be the southern portion of a large North-South s-shaped filament eruption along the central meridian of the Earth-facing disk. The southern portion of this filament appears to potentially lift off at about 2023-07-31T19:05Z roughly centered around S22E02. The northern portion of the filament eruption may be associated with another CME feature seen in the coronagraphs to the East.

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 |

These parameters track the front seen to the SW in SOHO LASCO C2, C3, and STEREO A COR2 imagery. There are many overlapping parts in the coronagraphs making it difficult to associate coronagraph features with potential corresponding solar disk eruptions. This CME is measured with an approximated longitude due to a lack of stereoscopic viewpoints. |
