St. Elmo's fire (also St. Elmo's light) is a weather phenomenon in which luminous plasma is created by a coronal discharge from a sharp or pointed object in an strong electric field in the atmosphere (such as those generated by thunderstorms or created by a volcanic eruption).
St. Elmo's fire is named after St. Erasmus of Formiae (also called St. Elmo, the Italian name for St. Erasmus), the patron saint of sailors. The phenomenon sometimes appeared on ships at sea during thunderstorms and was regarded by sailors with religious awe for its glowing ball of light, accounting for the name. Because it is a sign of electricity in the air and interferes with compass readings, sailors also regarded it as an omen of bad luck and stormy weather.
....it is also a 1985 movie named after the phenomenon starring members of the "brat pack."
....it is also the name of the main song from that movie.Source(s): Wikipedia
