 note = {Observations of E-W brightness distribution on the solar disk at 4000 Mc have been carried out with 8-element interferometer with quarter-wavelength plates since June 1954. In this paper the results of observations of the radio spots in 1955 are described. It was observed that the radiation from the radio spot has a small degree of circularly polarized component. The radio spot in the northern hemisphere radiated the excess of r.h. circularly polarized component in the east side of the central meridian, and in most cases the sense of the polarization reversed near the central meridian. The opposite sense was observed in the southern hemisphere. It was confirmed by direct measurement that the sense of polarization varies generally according to the rule found by Piddington and Minnett, i.e. it depends on the position of the radio spot and sunspot cycle. The value of % polarization usually does not exceed 10%.},
