Radio Emission Sources During Solar Eclipse on March 29 2006
On the base of eclipse observations the brightness temperature of undisturbed parts of solar disk was determined during the minimum solar activity between 23 and 24-th 11-year's cycles. The temperature was equal Td10.5=(43.7 plusmn 0.5) 103 K at wavelength 10.5 cm and Td12.0= (51.8 plusmn 0.5) 103 K at wavelength 12.0 cm. Radio brightness distribution above group of spots NOAA 0866 was calculated. It is shown that on both wavelengths the source consists of a compact bright nucleus with sizes about 50ldr103 km, having temperature Tb10.5=0.94ldr106 K and Tb12.0= 2.153ldr106 K, which are located at heights h10.5= 33.5ldr103 km and h12.0= =43.35ldr103 km above the spot, and extended halo with temperature Tb= (230-300)103 K, reaching the height of 157ldr103 km above photosphere. Thus, the eclipse observation on March 29, 2006 has allowed experimentally to determine the height of coronal condensation during minimum solar activity and to estimate physical parameters of plasma near to its top border.
