Evolution of the filament before, during, and after the eruption in Hα filtergrams from the GONG/NSO (panels a) − d)) and in AIA 304 images (panels e) − g)). Panel h) is a time-slice image obtained along the sector S1, dashed lines in panels e) and g). F1 and F2 indicate two mini-filaments. The plus shows the eruption center. The thick arrows indicate the falling material of the erupting filament. The temporal evolution in the AIA 304 Å as seen in the panels e) − g) is shown in the movie available in the online edition.
