Abstract : The authors measured the disk temperature of Venus at 608 MHz near the inferior conjunction of 1972 and obtained a value of 498 plus or minus 33K using a nominal CKL flux density scale. The result is consistent with earlier measurements, but has a much smaller uncertainty. Our theoretical model prediction is larger by a factor of 1.21 plus or minus 0.09. This discrepancy has been noticed previously for frequencies below 1400 MHz, but was generally disregarded because of the large observational uncertainties. (Author)
