Solar flares.
Abstract
Solar flares are discussed from three complementary viewpoints. The first is the radiative aspect which includes optical and radio observations, in addition to the magnetic circumstances of their origin. It is seen that flares are produced in regions of magnetic shear, a condition that arises mainly from sunspot motions. In this regard recipes for the prediction of flares are given. The second view point considers that flares produce great streams of energetic particles which carry away much of the flare energy. Gamma and X-ray studies of the spectra of these particles provide information on the flare's transient high-temperature plasma. A third consideration, satellite samples of flare-particle streams, provide diagnostic information on acceleration mechanisms pertinent to different kinds of flare event, while shedding complementary light on solar atmospheric composition at particular flare sites and on physical processes operating in the corona.
