Visible Phase Curves and Internal Heat Flow for Uranus

Images of Uranus acquired by Voyager 1 during the 1980s were re-analyzed using improved calibrations. These images provide disk-averaged reflectivities in six bands, at phase angles from 28 to 100 degrees. These, along with measurements made by the Voyager 2 spacecraft during 1986, are being used to constrain an atmospheric model of Uranus to generate a new bolometric Bond albedo for the planet in the 1980s epoch. Improved phase curves, atmospheric models, albedos, and a recomputed heat flow will be presented.
