The galaxy has been observed with the 6-meter telescope of SAO RAS using the SCORPIO spectropolarimeter. We explore the variability and lags in the polarized light of the continuum and broad H$\\alpha$ line. We give the Stokes parameters $Q, U$, degree of linear polarization $P$ and the position angle of the polarization plane, $\\varphi$, for 24 epochs.\n  We find a small lag~(10-40 days) between the unpolarized and polarized continuum that is significantly smaller t","authors_text":"A.I.
