We present three years of BVRI observations of the Algol Binary WW Cygni. These observations were made with the 16 inch telescope and SBIG ST-8 CCD of the Clyde Tombaugh Campus Observatory of New Mexico State University from 1997-1999. Our three year campaign enabled a good phase resolution and coverage for this 3.3178 day period binary. A model of the system is presented using the Wilson-Devinney eclipsing binary modeling code. A comparison of our photometric solution is made to a published spectroscopic solution (Yoon et al., PASP 106, 239). In WW Cyg we are fortunate to have almost a century's worth of data on the period of the system. Therefore we present an O-C curve and discuss its long term trends. This work is funded by the National Science Foundation.
