Note: CME with trianglular/trapezoidal shaped leading edge seen to the southwest in SOHO LASCO and farther to the west in STEREO A; was initially theorized to be associated with front-sided filament eruptions on the Earth facing disk in the southwest limb around 2024-12-19T22:00Z, however, triangulation suggests that this eruption is far-sided. Possibly associated with a far-sided eruption corresponding starting around 01:00Z that erupts distinctly different than the filament eruption seen in GOES 304 seen best in GOES 93/171/284 composite imagery off the southern limb and propagating to the southwest.

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.
