Red sprites, high-speed

Videonummer 12080886
HIgh-speed footage of red sprites. This footage was taken in 1998, using one of the earliest high-speed cameras. Red sprites are faint high-altitude electric discharges. They are triggered by positive cloud-to-ground lightning in the storm below. They can rise to heights of 97 kilometres, reaching the bottom of the ionosphere and the edge of space. They last for a few thousandths of a second, and are only visible under the right conditions. Their existence was only confirmed in 1989 and their formation is still not fully understood. Filmed in Colorado, USA.
