Abstract:

Results of observations of solar eclipses at cm and dm wavelengths are considered, which are related to emission sources above spot groups on the sun and to brightness temperature distribution on the limb of the solar disk. The analysis of the data obtained made it possible to determine that in the sources observed the emission spectrum showed a sharply defined maximum in the wavelength region between 4.5 and 7.5 cm. A dependence between size and height above the photosphere of the sources and the wavelength is inferred. Conclusions are drawn on the nonlinearity of the dependence between the radiative flux of the source and the area of the corresponding spot group. Comparison of results of observations, carried out at low solar activity, allow it to be stated that the increase of brightness temperature at the edge of the solar disk at 3.2 cm does not exceed 20 percent. Little dependence of the solar radioradius on the wavelength is observed for 2 lambda 10 cm. Author
