Abstract
We present a new period study and light-curve solutions for the A-Type W UMa binary GSC 3208-1986. Contrary to a previous claim by R.G. Samec et al. of a rapidly decreasing period, the system's period is increasing moderately on a timescale of 2x 10^6 years. The light curve is variable on the time scale of years, which can be understood by changes in how much it overfills its Roche lobe.
