3-part CME


3-part CME (loop, cavity, core) ejected in southwest, superposed on helmet streamer. CME moving at a modest speed of ~310 km/sec with an acceleration of ~24 m/sec^2 as it leaves the K-Cor field of view.

Subtraction movies show lateral expansion of base of CME in low corona; while width of ejected material is not as wide. Part of core material does not escape (i.e. falls sunward); best seen in subtraction movies.
