Composites of EUVI 195 Å and COR1 white light running difference images illustrating the evolutions of the flare, the filament eruption, the EUV wave and the CME. The upper panels are the STEREO-A observations, the lower panels the STEREO-B data. The white line in a) and the black line in e) present the eruption directions of the filament observed by STEREO A and B satellites, respectively. The FOV is 2.8 R_⊙ × 2.8   R_⊙.
