Radio Observation of the Partial Solar Eclipse at 21.1 cm Wavelength in Kunming on September 23, 1987

A radio intensity measurement was performed with a radio telescope of 21.1-cm wavelength when the track of Partial solar eclipse passed over Yunnan Observatory in Kunming on September 23, 1987. 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 arc given in this paper. The emission measure of the halo N²L above the plage is calculated to be 2.5~4.4×10²⁸ electron₂/cm⁵.
