We present the results of long-term spectropolarimetric and spectroscopicmonitoring of MWC 314, a candidate Luminous Blue Variable star. We detect thefirst evidence of H$\alpha$ variability in MWC 314, and find no apparentperiodicity in this emission. The total R-band polarization is observed to varybetween 2.21% and 3.00% at a position angle consistently around$\sim0^{\circ}$, indicating the presence of a time-variable intrinsicpolarization component, hence an asymmetrical circumstellar envelope. We findsuggestive evidence that MWC 314's intrinsic polarization exhibits awavelength-independent magnitude varying between 0.09% and 0.58% at awavelength-independent position angle covering all four quadrants of the StokesQ-U plane. Electron scattering off of density clumps in MWC 314's wind isconsidered as the probable mechanism responsible for these variations.Comment: 19 pages, 6 figures, accepted in PAS
