[76.14] Three years of photometric monitoring of the Algol Binary WW Cygni

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.
