Research of blazars at the Astronomical observatory of Belgrade

Abstract

At the beginning of 2013, we have a team of scientists at the Astronomical Observatory of Belgrade, focusing on observations and research of blazars. At the same time, we established a cooperation with the Astronomical Observatory of Torino (Osservatorio Astrofisico di Torino), center for the Whole Earth Blazar Telescope (WEBT) international collaboration. In this paper, we describe the WEBT project, present our equipment as well as some preliminary results. We also point to some issues that we have encountered during the one year experience and found important from the observational point of view.
