SPRITE?
http://elf.gi.alaska.edu/sprites.html
A movie of a sprite is available (157K mpeg).
Early research reports for these events referred to them by a variety of names, including “upward lightning,” “upward discharges,” “cloud-to-stratosphere discharges,” and “cloud-to-ionosphere discharges.” Now they are simply referred to as sprites, a whimsical term that evokes a sense of their fleeting nature, while at the same time remaining nonjudgemental about physical processes that have yet to be determined.
