✦ Synopsis

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 condensation, originally at 2-3 • l0 s K, is raised to the temperature of about 4-5 • 106 K and is responsible for soft X-ray enhancement.

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
