12th August morning apparently for the first time over the Czech Republic managed to capture cloud type lightning Troll. Trolls are such rare affinity sprites. They occur after the distinctive Red sprites at lower altitudes above the Earth's surface (30-50km) and in the form of bright spots are slowly moving upwards. Troll is a so-called secondary TLE and the name is an abbreviation of Transient Red Optical Luminous Lineament. But it is still uncertain whether this is a tendrils, and they are actually pulling over the tops of the storm clouds, or possibly Troll emerging from the storm cloud in response to the Red Sprites.
