Flares

 Flares are the most violent eruptions on the Sun. They occur in the chromosphere and corona above complex sunspot groups. During a flare temperature in the region rises to 5 million kelvins. Vast quantities of particles and radiation are released into space. The flare lasts no more than 20 minutes. Flares are the result of magnetic field stress and are seen most often where lines of opposite polarity conflict.
