The estimates of quiescent and flare time temperatures of soft X-ray emitting regions on the Sun are obtained for flares observed during March--August 1967 from X-ray observations in two soft X-ray bands, 2-12 It (Explorer-33 data) and 8-12 A (OSO-3 data). It is concluded that hot coronal condensati

โฆ Synopsis
Soft X-ray flare data in the wavelength range 2.6-10 A are used to examine the time variation of emission measure and electron temperature. The thermal plasma parameters were derived according to a two-temperature model proposed by Herring and Craig (1973). Estimates of electron density and source volume are made by assuming conductive and radiative cooling mechanisms. It is suggested that the present observations imply a multi-thermal interpretation of the soft X-ray flare.

A study is made of several ATM flares, to investigate the effect of soft X-ray heating at chromospheric levels. It is shown that the amount of energy released in Lya and Lyman continuum emissions, and their spatial and temporal behavior, in compact flares correspond to what is expected from model ca
Processes leading to the excitation of soft X-ray line spectra are discussed in relation to their thermal or non-thermal nature. Through analysis of calcium spectra from the XRP experiment on SMM, it is shown that the ionization balance during the gradual phase of flares is effectively in the steady
