We report on over 13 years of optical and near-ultravioletspectropolarimetric observations of the famous Luminous Blue Variable (LBV), PCygni. LBVs are a critical transitional phase in the lives of the most massivestars, and achieve the largest mass-loss rates of any group of stars. Usingspectropolarimetry, we are able to learn about the geometry of the nearcircumstellar environment surrounding P Cygni and gain insights into LBVmass-loss. Using data from the HPOL and WUPPE spectropolarimeters, we estimatethe interstellar polarization contribution to P Cygni's spectropolarimetricsignal, analyze the variability of the polarization across the H$\alpha$emission line, search for periodic signals in the data, and introduce astatistical method to search for preferred position angles in deviations fromspherical symmetry which is novel to astronomy. Our data are consistent withprevious findings, showing free-electron scattering off of clumps uniformlydistributed around the star. This is complicated, however, by structure in thepercent-polarization of the H$\alpha$ line and a series of previouslyundetected periodicities.
