We report on our 1999 May 15 to 19 UT observations of the irregular Uranian satellite Sycorax (S/1997 U2) and the short period comet nucleus P/Neujmin 1 with the 1.8-m Vatican Observatory telescope on Mt. Graham, Arizona, a high quantum efficiency CCD camera, and B, V, and R filters. We present V magnitudes, B-V and V-R colors, and lightcurves for Sycorax and P/Neujmin 1. Our measurements allow us to constrain the diameters, surface compositions, and shapes of these two objects. We compare the physical properties of Sycorax and P/Neujmin 1 to their possible progenitors, Kuiper belt objects.
