Voyager 2 images of Phoebe obtained over a period of 24 hours provide information on the size, rotation rate, surface marking and photometric properties of this mysterious object. Phoebe is approximately euqidimensional; it longest diameter, ~230 Km, is only 10% greater than the shortest diameter (~210 km). A prograde rotation period of 9.4¿0.2 hours was determined from both the disk-integrated light curve and by trucking individual markings. Because of the limited resolution of the images (11 pixels across the disk) crater counts cannot be made. The geometric albedo of Phoebe is longitudinally variable from 0.046 to 0.060 (clear filter, &lgr;=0.47 &mgr;m). The most prominent surface marking are brighter patches at high northern and southern latitudes and have reflectances as much as 50% greater than the dark, bland areas. These patches are scattered and do not appear to constitute polar caps. The Voyager color data agree with earlier ground-based spectra that show that Phoebe has a flatter spectrum than does the dark side of Iapetus; this observation is not consistent with simple contamination of of Iapetus by debris from Phoebe.
