Heavy Thunderstorm Sprites above Czech Republic

On May 26, 2011, Martin Popek filmed sprites above an area with heavy thunderstorms preceding a cold front in Nydek (Eastern part of Czech Republic) with its video camera (Watec 902h2 ultimate + lens 8/1,3). The radar map (1-2) shows the position of the observer and the approaching thunderstorm front.

More stills and the videos can be found here (1-2-3).
