A solar flare is a sudden brightening observed over the Sun surface or the solar limb, which is interpreted as a large energy release of up to 6 × 1025 joules of energy[1] (about a sixth of the total energy output of the Sun each second). The flare ejects clouds of electrons, ions, and atoms through the corona into space. These clouds typically reachEarth a day or two after the event.[2] The term is also used to refer to similar phenomena in other stars, where the term stellar flare applies.
