Abstract

Abstract: We present results from an original observational campaign comprising five epoch optical photopolarimetrical observations of the BL Lac-type AGN OJ287 in the period 2012 November–2013 April. The data are gathered with the Focal Reducer Rozhen 2 (FoReRo2) on the 2-m RCC telescope at NAO Rozhen, Bulgaria. We derive photometry and polarization in the R band as well as position angle (PA). There are indications for correlation between polarization and brightness in the R band. Furthermore, observed variation in PA corresponds to a rotation of the plane of polarization of 5.80 deg d −1 .
