Analysis of ZDC SMD data shows that it may be used as a local polarimeter is presented in the attached report.  Data from special 2004 ZDC runs were analyzed and found to produce a large left-right asymmetry from transverse beam polarization.  The asymmetry was also plotted as a function of azimuthal angle and displayed a sinusoidal pattern consistent with results from other experiments.  These results demonstrate the capability of using the ZDC SMD as a local polarimeter for STAR.
