An odd TLE detection from Central Europe

A huge thunderstorm swept through the common borders of Germany, Poland, and the Czech Republic in Central Europe on the night of 2 July, 2012. The storm was producing TLEs all night. Martin Popek from the Czech Republic has set his camera in Nydek to watch the firework of sprites. The TLE camera in Sopron was monitoring the same thunderstorm, too.

Several sprites have been captured by both cameras, but around 20:40 UTC the system in Nydek recorded an odd sequence of emissions which was missed by the camera in Sopron. Flame-like emissions were shooting upwards. See the video! Comments are welcome.
