Sprite (lightning)

Sprites are a type of upper-atmospheric lightning that occurs high above thunderstorms, typically at altitudes of 50 to 90 kilometers (31 to 56 miles). They are a form of transient luminous event (TLE) and are characterized by their reddish color and tendrils that extend down toward the clouds. Sprites are generally associated with large thunderstorms, especially those that produce powerful cloud-to-ground lightning strikes.
