solar flare

n.
A sudden eruption of magnetic energy on or near the surface of the sun, usually associated with sunspots and accompanied by bursts of electromagnetic radiation and particles. Ultraviolet and x-ray radiation from solar flares often induce electromagnetic disturbances in the earth's atmosphere.

solar flare

n
(Astronomy) a brief powerful eruption of particles and intense electromagnetic radiation from the sun's surface, associated with sunspots and causing disturbances to radio communication on earth. Sometimes shortened to: flare See also solar wind

n.
a brief, sudden brightening of the sun's atmosphere that accompanies a burst of radiation from a sunspot.
