Abstract:Well sampled light curves of BL Lac objects are very useful to understand the physical processes responsible for the highly variable emission from this class of AGN. The best way to perform the necessary high number of observations is the use of automatic small aperture telescopes. We present some results of the Perugia-Roma monitoring program concerning the recent active phase of BL Lac and the Intra-Day Variability of S5 0716+714. This revised version was published online in July 2006 with corrections to the Cover Date.
Keywords:BL Lac objects: BL Lac  S5 0716+714
