The upper atmospheric structure of Uranus revealed in the occultation of the bright star SAO 158687 by the planet on March 10, 1977 is reported. Light curves obtained using a photometer on a 0.46-m reflecting telescope were analyzed using the inversion method of French, Elliot and Gierasch (1977) to derive the number density, pressure and temperature of the occulting atmosphere. The mean temperature of the inverted section of the profile is found to be 87 K for immersion and 90 K for emersion in a strongly nonisothermal atmosphere exhibiting wavelike temperature variations with scale height. Variations of 40 to 50 K are observed within a vertical length scale of about 150 km. Further work is indicated to determine the reason for the low observed temperature relative to Neptune (140 K) and the processes responsible for the wavelike temperature variation.
