CMEs and filament/prominence eruptions are also strongly related (Gopalswamy et al., 2003; Jing et al., 2004, and references therein), and part of the erupting filament becomes the bright core of the CME, with the remaining part falling down to the solar surface. The association rate derived from observations depends on the observational sample and the wavelength.
The strong association between CMEs and flare/filament eruptions paved the way to construct the CMEs models from the heritage of flare and filament researches. It is now believed that, when they are associated, flares and CMEs are different aspects of one global magnetic eruption (Harrison, 1995; Forbes, 2000; Zhang et al., 2001a).
