Abstract

We have started automatized photometric monitoring of active galactic nuclei using the 46 cm telescope of the Wise Observatory in Israel. The telescope is specially equipped with narrow-band filters to perform high-fidelity photometric reverberation mapping of the accretion disk in V < 17 mag sources up to z ∼ 0.1. Here, we describe the capability and accuracy of the experiment, and present the first science verification data obtained for the Seyfert 1 galaxy Mrk 279. With sub-diurnal sampling over more than two months, and typical flux measurement uncertainties of 1%, we are able to measure inter-band time-delays of up to ∼ 2 days across the optical range.
