Filament interaction with the hot arcade above. Panel (a): MGN time-distance plot along the slit (Fig. 10k). Panel (b): AIA 304 Å light curves for the maximum and average brightness within BHF. Vertical dotted lines mark the time of occurrence of the SPDBs (Table 1). Panels (c–f): BHF formation and movement of the filament leg with respect to the dark structure (white circle) in AIA 304 Å at similar times as in Fig. 10.
