Photometric lightcurves were obtained during the 2002, 2004, and 2005 apparitions of the Vesta family asteroid 2511 Patterson using the 1.8-meter Vatican Advanced Technology Telescope (VATT) and the CTIO 1.0-meter. Analysis of these data yields a rotational period of 4.141 ± 0.001 hours and the following color indices: B-V = 0.91 ± 0.01, V-R = 0.50±0.01, and V-I = 0.81 ± 0.01. In addition, from January-May 2004, photometric data were aquired over a range of solar phase angles where a linear trend of 0.028 ± 0.001 mag/deg was observed in the asteroid's mean R magnitude. At low phase angles during March 2004, Patterson's lightcurve displayed an amplitude of approximately 0.7 magnitudes. Assuming a triaxial (a>b>c) ellipsoid model for its shape, this implies a minmum a/b axial ratio of 1.9. After observations from the 2005 apparition are completed, these will be combined with the previous data to develop a more complete shape model. This study will help place constraints on models for formation mechanisms of 2511 Patterson and the other Vesta family asteroids.
