AGN monitoring with the MAGIC telescope in 2007 — Ching-Cheng Hsu¹, •Konstancja Satalecka², Elisa Bernardini², Florian Goebel¹, Pratik Majumdar¹, Martin Tluczykont², and Robert Wagner¹ for the MAGIC collaboration — ¹Föhringer Ring 6, 80805 München, Germany — ²Platanenallee 6, 15738 Zeuthen, Germany

Long term monitoring observations of TeV Blazars can provide an important input to constrain theoretical models concerning blazar jet physics. They are also essential for the determination of flaring state probabilities to estimate the statistical significance of possible correlations between flaring states and other observables such as neutrino events. Last but not least AGN monitoring allows one to trigger multiwavelength ToO observations.

In 2007 the MAGIC telescope has monitored three TeV Blazars: Mrk501, Mrk421 and 1ES1959. For each source up to 40 measurements, evenly distributed over a whole observation period, were performed. Each measurement lasted 30 to 60 minutes which allows to constrain fluxes as low as 25% of Crab flux. We present a preliminary results of those observations.
