We present light curves and analyses of the RS CVn eclipsing system UV Psc. Greenwood (1981, M.S. thesis San Diego State University) obtained uvby photoelectric data at Mount Laguna Observatory in 1980 using the 0.4-m telescope. Because this system has a strongly variable light curve and the data is unpublished, we reanalysed these data using the physically more realistic models of Wilson-Devinney and the ELC program (Orosz, J. A., & Hauschildt, P. H. 2000 A&A, 364, 265). Both modeling programs yielded similar results, which were also consistent with other published results (Kjurkchieva, et al. 2005 AJ, 129, 1084). The determination of the global parameters was somewhat affected by the night to night variations typical of RS CVn systems. A new time of primary minimum was determined. This determination was consistent with other minima reported during this time period (Shengbang, et al. 1999, Ap&SS, 266, 259).
This work was supported in part through an REU grant (AST-0453609) to SDSU.
