Abstract:

The two-element interferometer at the Owens Valley Radio Observatory was used in September, 1967, to measure the 3-cm brightness and polarization distributions of Venus near inferior conjunction. The limbs were found to be unpolarized to a very low upper limit. Limb-darkening was observed, but no departures from circular symmetry could be detected. Apparently the Venus atmosphere supplies most of the radiation observed at this wavelength. Venus was also observed briefly at 7.5 cm with low resolution. Author
