Top Photo: Sprites.
Enigmatic pillars of luminosity tower above a distant thunderstorm.
An amplified CCD video camera recorded these displays during 1995
from a field site near Fort Collins, Colorado.
A few lights mark the horizon, above which distant overcast is
silhouetted by glow from intense lightning associated with the sprites.
These high-altitude phenomena typically last a few tens of
milliseconds and exhibit a characteristic structure of
delicate tendrils merging into a vertical column.
The sprite is topped by a diffuse crown spreading into the lower
ionosphere(~90 km).
