Evolution and structure of the flare-active region HR 16631 (February 1980) based on RATAN-600 observations.
The evolution of a local radio source associated with flare active solar region HR 16631 (February, 1980) is considered based on the RATAN-600 observations at five wavelengths in the range of 2 - 4 cm. It is shown that during the period of high flare activity of the sunspot group a peculiar detail associated with the place of the highest gradient of the photospheric magnetic field appears and dominates in the local radio source structure. This peculiar source is connected with the region of the emerging new magnetic flux. The peculiar source has a steep spectrum, moderate (20 - 40%) degree of circular polarization. The characteristics of this source proved to be very stable for three days of its existence.
