Mayer, McCullough, and Sloanaker [1] and Drake and Ewen [2] have measured centimeter wavelength radiation from several of the planets; the former at 3.15 and 9.4 cm, the latter at a wide bandwidth centered near 3.75 cm. The first measurements were the observations of Venus by Mayer et al., made near inferior conjunction in late spring 1956. These were obtained with a sufficiently favorable signal-to-noise ratio to permit direct recognition of Venus in individual diurnal-rate scans, and a brightness temperature of 560 ± 73°K (mean error) was deduced for the planet at inferior conjunction, i.e. for the dark side of Venus.
