 note = {The partial and annular eclipse on 19 April 1958 was observed at Toyokawa and Hachijojima at four frequencies, i.e. 9400, 3750, 2000 and 1000 Mc/s. Brightness distribution over the solar disk at these frequencies is derived with the aid of interferometric observations at 4000 Mc/s in full course of the eclipse. The maximum brightness was, from 9400 to 1000 Mc/s, of the order of 10^5, 10^6, 2X10^6 and 3x10^6°K respectively. It is very remarkable that the source of polarization is strictly confined in a small area over the sunspot, about 1' in diameter. Thus, two sources of polarization of different sense exist over each pole of a bipolar sunspot. The polarization seems to be determined at a lower altitude than what has been considered. Most of the sources have the sense of extraordinary wave, though some have an opposite sense at 9400 Mc/s. The degree of polarization increases with frequency: the value for the most active spot amounts to more than 60% at 9400 Mc/s, while at 1000 Mc/s, it is subject to nothing.},
