flare

A bright, transient event within the sun's chromosphere and corona.

Flares produce enhanced emission at radio frequencies and in the ultraviolet and x-ray spectral regions as well. They may also produce increased particle emission, often with ions of cosmic ray energies. Flares usually appear within minutes and fade within an hour. They are localized to small areas (typically <10-3 of the solar disk) and usually occur within solar active regions.
