sprelve

plural sprelves

1. astronomyAn upper atmospheric optical phenomena associated with thunderstorms, in which an elve is immediately followed by a sprite.

   In the early days of LLTV monitoring it was common to observe an apparent elve followed by a sprite, sometimes called a "sprelve." While elves do indeed precede some sprites, the "sprelve" in most cases, was found to represent a "sprite halo."
