For targets will be visible any time of the year ({\bf see plot}). For calibration purposes, some time will be scheduled for observations of the Crab nebula.  The blazar observations will allow \item to cooperate with the Whipple monitoring telescope for an extended time coverage. \item to prompt Target of Opportunity (ToO) observations with MAGIC in \item to prompt Target-of-Opportunity (ToO) observations with MAGIC in the case of flares increasing time resolution.

Silicon PM) as photon detector in the camera of a Cherenkov telescope. The advantages are extremely high quantum efficiency (>50\%), easier gain stabilization and simplified application compared to classical PMs. If these test measurements are successfully finished until 8/2008 we consider to use APDs in favor of classical PMs. The design of such a camera would take place at University Dortmund in close collaboration with the experts from ETH.
