| Abstract: | Radiometric measurements of Venus at a wavelength of 6 cm made in the period from November 1965 through March 1966 indicate that the disk temperature reached a minimum of 630 ± 30°K soon after inferior conjunction. An observation of Mars near opposition in 1965 gave a disk temperature of 190 ± 60°K, the same as that reported by Kellermann. The disk temperature of Jupiter remained essentially constant at 291 ± 25°K from March 1965 through March 1966. Saturn was found to have a disk temperature of 190 ± 45°K, which is slightly higher than anticipated. |
