Abstract
We have examined the time profile of the flare heating function based on an analysis of evolutionary paths in the emission measure-temperature diagram. Three limb flares on 29 June 1980 have been selected for the analysis. The observations consist of the soft X-ray spectra and images obtained by instruments placed aboard the Solar Maximum Mission (SMM) satellite. The emission measures and the temperatures have been derived from the CA XIX soft X-ray spectra obtained by the Bent Crystal Spectrometer (BCS). The images obtained by the Flat Crystal Spectrometer (FCS) have been used to estimate the size of one of the flares. We illustrate how the behaviour of the emission measure-temperature diagram allows one to study the rate of energy deposition during both the rise and decay phases of the flare evolution.
