✦ Synopsis
The amount of circular polarization of the total solar radio emission at 7 GHz present permanent changes after the occurrence of certain radio bursts associated with larger flares. For isolated S-components, associated with such flares the changes of the polarization degree AHs ranges between 0.004 to 0.1, and appears to be a function of the flare importance. A semi-qualitative interpretation associates AHs with magnetic field reductions at the S-component, agreeing fairly well with a flare mechanism based on collisionless dissipation of magnetic energy, corresponding to energies in the range of 1030 to 103z ergs, assuming an average model for the coronal condensations.
