Photometry of Uranus and Neptune, 1972-2016 By G. W. Lockwood/Lowell Observatory

    This dataset contains the results of a systematic effort to obtain the seasonal variations of the disk-integrated albedos of these objects, consisting determination of Strömgren b(473 nm) and y(551 nm) opposition magnitudes made at Lowell Observatory at each apparition from 1972 to 2016.

    All the tabulated and plotted planetary magnitudes have been adjusted to zero degrees solar phase angle and fixed heliocentric planetary distance, 19.191 AU for Uranus and 30.071 AU for Neptune. The data are described in an accompanying document, which provides summary tables (including approximate sub-earth latitudes).
