Classification of Solar Flares

Abstract

This paper is organized as follows. First we discuss the historical background before the SMM (Solar Maximum Mission) launch. Next we discuss the recent developments made by observations with SMM, Hinotori, and other contemporary satellites and ground-based observatories. Based on these observations, we classify solar flares into the following five classes: thermal hard X-ray flares, nonthermal hard X-ray flares, impulsive gamma-ray/proton flares, gradual gamma-ray/proton flares, and quiescent filament-eruption flares. We also discuss the roles of filament eruptions in flare development. Finally we discuss theoretical ideas related to processes occurring in different classes of flares.
