TEMPERATURE OF VENUS

Abstract

Radio emission from Venus was measured with a 22-m radio telescope during the period of inferior conjunction in 1961. From the middle of March to the beginning of June, observations were made at wavelengths of 4 and 8 mm and 9.6 cm and from 26 May through 10 July, at the 3.3cm wavelength. The shifting of the brightness temperature minimum from the point of inferior conjunction to the eastern elongation indicates that the rotation of Venus occurs in the same direction as its revolution around the sun. The shifting is also considered to support the hypothesis that the rotation period is not equal to the revolution period. The wide variations in temperature may be attributed to changes in electron accumulations in the Venusian ionosphere.
