At Kagoshima and Toyokawa, the moon covered a large sunspot group in the southern hemisphere and a considerable decrease in flux was observed. The interferometric observation at Toyokawa isolated the variation in flux of the enhanced region and the other area. The reductions were carried out almost independently by two institutions, but came out with remarkably identical results. The size of the region over the sunspot is about 4' and the brightness temperature is of the order of 10°K. It is also to be remarked that any brightness distribution with radial symmetry for the quiet sun is not consistent with the observed eclipse curve.}, pages = {84--95}, title = {A MODEL FOR THE SOLAR ENHANCED REGION AT CENTIMETER REGION DERIVED FROM PARTIAL ECLIPSE OBSERVATIONS}, volume = {3}, year = {1956} }
