Examples of sprites and sprite halos imaged by the University of Alaska from the Wyoming Infrared Observatory, Jelm Mountain, WY in 1999. The last example shows reignition of a sprite after ~50 milliseconds. Playback speed is 1/100 real time. A detailed analysis of Event #6 is contained in D.D. Sentman et al. (2008), Plasma chemistry of sprite streamers, J. Geophys. Res., 113( D11112), doi:10.1029/2007JD008941. (Music: excerpt from Beethoven's Violin Concerto.)
