ball lightning
No scientific documentation such as photos, videos, or other recordings of ball
lightning exist, so experts have had to rely on eyewitness accounts,
which have been numerous. Judging from such accounts, balls of lightning are
typically between a golfball and a basketball in size, about as bright as a
60-watt light bulb, and often red, orange, or yellow in color. Observed
shooting through the air, across the ground, and or even into houses, they are
fleeting, generally lasting a few seconds before vanishing gradually or
abruptly.
