Spatial evolution of the eruption using the running difference method (a–e) and with MGN processed images of the prominence eruption in AIA 304 (f–j) and 171 (k–o) Å wavelengths (see Sect. 2.1). The northern and southern legs of the filament are indicated by arrows in panels h and i, respectively. The flare loops represented by “hot loops” are shown in panel j. The black and cyan arrows in panel h show the outer and inner quasi circular features which is the FR configuration. See online movies.
