Abstract
The results of microwave observations of the solar eclipse of March 29, 2006, with the RATAN-600 radiotelescope are presented. The observations were carried out using the northeastern sector of the radiotelescope in a broad wavelength range (1.03, 1.38, 2.70, 6.20, 13.00, and 30.70 cm) in the intensity channel. The aim of the present work is to conduct a comparative analysis of the distributions of brightness temperatures in the solar atmosphere at a distance (ranging from one to two solar radii) from the center of the optical solar disk. The data for the analysis come from the RATAN-600 observations of the solar eclipse of March 29, 2006, earlier observations with the RATAN-600 radiotelescope, and calculations of brightness temperatures that were carried out using the Baumbach-Allen formula which describes the electron density in the solar corona. The differences between the distributions obtained by the above-mentioned methods are discussed.
