The 8-14-μ Appearance of Venus Before the 1964 Conjunction

Abstract

In an earlier paper (Murray, Wildey, and Westphal 1963) we have described the detailed mapping of the 8-14-μ radiation from Venus using the 200-inch Hale telescope. This paper extends that work over a period of about 7 months from December 15, 1963, to June 6, 1964. Detailed maps for 6 days are presented that show the morphology of the upper-atmosphere brightness temperature and illustrate a number of anomalous features near the cusps. The problem of atmospheric extinction and the derived brightness temperature is discussed.
