Sprites and Jets- Electrical discharges that occur high above active thunderstorms. They have been found to occur in conjunction with and/or as a reaction to a normal cloud-to-ground lightning discharge. They are swift and faintly lit, making them almost invisible to the naked eye. Observations of sprites and jets have been made by placing a telescope on a high mountain and aiming it above thunderstorms occuring hundreds of miles away. For more information and photos on sprites and jets, check the Lightning Links page.
