solar flare

(sudden brightening of the Sun)

A solar flare is a sudden brightening of the Sun. Other stars also flare (stellar flares). Solar flares vary in brightness and the energy presumed to be released. They can affect power and communications on Earth. They are generally assumed to be the results of magnetic reconnection in the Sun's magnetic field, a plausible but complex process and current models are limited in how much observed detail they match.
