FACT - long-term monitoring and flare alerts — •Katja Meier for the FACT collaboration — Universität Würzburg

One of the major goals of the First G-APD Cherenkov Telescope (FACT) is the long-term monitoring of bright TeV blazars. With these data, flare studies are carried out in order to better understand the underlying physics of these extremely variable objects. In case of enhanced activity in one of the monitored objects, an alert to more sensitive instruments is sent. To send such triggers in almost real time, a quick look analysis on site has been set up providing excess rate curves. As the excess rate depends on the zenith distance and the level of night sky background light of the observation, these effects have been studied with data taken on the Crab Nebula.

Results from this study and the quick look analysis will be presented.
