Abstract

We have detected time variation in Titan's geometric albedo in methane windows at 0.94, 1.08, and 1.28 μm, relative to its albedo in adjacent methane bands, of 8 ± 5%, 14 ± 3%, and 22 ± 3%, respectively. We attribute these changes to a surface feature or a feature near the surface. Our observations are consistent with synchronous rotation and can be explained by a higher surface albedo by 0.1 on Titan's leading hemisphere.
