Resumo
The results of the analysis of a solar radio burst based on RATAN-600 observations in the 1.0-1.5 GHz range with a high spectral resolution are discussed. It is suggested that the energy release in the region of coronal bright points was caused by magnetic reconnection accompanied by electron acceleration and the development of plasma turbulence. In this paper, the radio emission of the burst is considered as the result of the merging of plasma waves that form transverse electromagnetic waves observed at RATAN-600. Plasma wave spectra were obtained for different moments of time, allowing simulation of the measured radio burst emission spectra.
