SOME DECIMETER OBSERVATIONS OF VENUS DURING THE 1962 CONJUNCTION

Abstract : The flux from Venus was measured at various frequencies, giving blackbody disk temperatures of 580 degrees K = 60 degrees at 10.7 cm, 596 degrees K = 100 degrees at 18 cm and 616 degrees K = 100 degrees at 21 cm. An attempt was made to measure the size of the planet at a wave length of 9.4 cm with an interferometer with a baseline of 5184 wavelengths aligned east-west. Only a very small part of the amplitude-spacing spectrum was observed, but the observations are not what would be expected of a uniform or limb darkened disk.
