Filament and jet evolution on January 1, 2014 (event 2), in AIA 171 Å (top row), AIA 304 Å (middle row), and Hα (bottom row). The null-point-like structure is shown with a white arrow in panel a at the top of the dome-like structure. The jet propagation from this null-point towards the filament channel is shown with black arrows in panels b and e. The cyan arrows in panels c and f show the later brightening associated with the jet, which reinforces the oscillations. The filament is very well observed in Hα as a dark long structure shown with black arrow in panel g indicating the sinistral handedness of the filament. The contours of the filament observed in Hα are over-plotted in AIA 171 and 304 Å channels in panels a, b, and d. The black contours in panels e and h are for the brightening at the jet base observed in Hα over-plotted in AIA 304 Å.
