Occurrences of the flare-associated microwave bursts as well as their peak flux and energy excess spectra have been examined in relation to the pre-and post-maximum phases of the respective flares during the period 1969-72. Results obtained are: (i) about 76 % of the flare-associated bursts occur in

β¦ Synopsis
A surprisingly good correlation has been found for SPA measured at VLF propagation (&b) and 7 GHz solar microwave burst energies (E~,). The data are correlated in the form A4~ = a log U~, + b and include all kind of solar events, irrespectively from type, complexity or duration. Soft X-ray peak fluxes (Ix) have a known similar correlation to SPA, and a functional relationship of the form E~,-I~ can be established. As one practical application, the energies from solar events can be reasonably well inferred from SPA data, which are quite reliable and easily obtainable.

In the present paper we report the results of a correlation analysis for 57 microwave impulsive bursts observed at six frequencies in which we have obtained a regression line between the peak frequency and the corresponding rise time of microwave impulsive bursts: fp~ 1.517 x 101~ TM (with a correla
