Sprites are extreme high altitude lightning

I actually first about sprites when my students were doing our research projects. Sprites how are extreme high altitude lightning displays. These remarkable electrical displays can sometimes be photographed as this one was at 80 km. See the photo and directions how to do sprit chasing and look for the phenomenon.
