Hot regions in solar flares produce X-radiation and microwaves by thermal processes. Recent X-ray data make it possible to specify the temperature and emission measure of the soft X-ray source, by using, for instance, a combination of the 1-8 A (peak response at about 2 keV) and the 0.5-3 ]k (peak r

โฆ Synopsis
Results of simultaneous high-resolution microwave and X-ray two-dimensional imaging observations are briefly reviewed. It is shown that seven events published in the literature are not homogeneous but rather diverse with respect to spatial structure, mutual relations on position or shape. An outlook is presented for the next solar cycle to obtain a large data set for extensive study of energetic solar phenomena.

We have compared microwave imaging data for a small flare with simultaneous hard X-ray spectral observations. The X-ray data suggest that the power-law index 5 of the energy distribution of the radiating electrons is 5.3 (thick-target) which differs significantly from the estimate (b = 1.4) from a h
Simultaneous microwave and X-ray observations are presented for a solar flare detected on May 8, 1980 starting at 19:37 UT. The X-ray observations were made with the Hard X-Ray Burst Spectrometer on the Solar Maximum Mission and covered the energy range from 28-490 keV with a time resolution of 10 m
