a)g) SDO/AIA EUV images in the 304 Å channel (T ~ 0.05 MK) showing the eruption of a kinked small filament associated with the C3.9 flare on 30 April 2012. N and S represent the northern and southern legs of the filament. The blue arrows show the unwinding motion of the northern leg and the top portion of the filament. X and Y axes are in arcsecs. h) Space-time plot along the slice A (shown by the dotted line in panel f)) plotted with AIA 304 Å mean counts in blue curve. i)k) Apparent velocity field computed with DAVE using AIA 304 Å images, showing the plasma flows in and around the prominence threads. The longest arrow (in the panels) corresponds to a speed of i) 204 km s-1, j) 178 km s-1, and k) 158 km s-1. The temporal evolution of the kinked filament in 304 Å can be found in the online movie.
