Radio Observation of the Partial Solar Eclipse at 10.6 cm Wavelength in Kunming on September 23, 1987

The partial solar eclipse was observed with a radio telescope of 10.6 cm wavelength of Yunnan Observatory in Kunming at time when the solar annular eclipse of September 23, 1987 occurred in the central part of China. Some preliminary results deduced from this observation arc discussed. The correlations of radio sources with sunspot, filament, prominence, and plage are examined. The flux densities，two-dimensional sizes, heights and brightness temperatures of eight regions are given in this paper. The emission measure of the halo N²L above the plage is calculated to be 6.3~6.9×10²⁸ clectron²/cm⁵.
