A rare and curious form of lightning, not yet well explained, is called ball lightning, and it consists of balls, or luminous masses, which move at moderate speeds and last for a few seconds. Disturbing effects on radio equipment, called noise or static, can originate from electrical discharges in the form of lightning; and thus the position of distant storms can be determined using two or more oscillographs or radio directional equipment located at known distances from each other.]
