Abstract (from CDS):

New data from the optical monitoring of γ-ray loud blazars at the Torino Astronomical Observatory are presented. Observations have been taken in the Johnson's B, V, and Cousins' R bands with the 1.05m REOSC telescope equipped with a 1242x1152pixel CCD camera. Many of the 22 monitored sources presented here show noticeable magnitude variations. Periods corresponding to pointings of the Energetic Gamma Ray Experiment Telescope (EGRET) on the Compton Gamma Ray Observatory (CGRO) satellite are indicated on the light curves. The comparison of our data with those taken by CGRO in the γ-ray band will contribute to better understand the mechanism of the γ-ray emission. We finally show intranight light curves of 3C 66A and OJ 287, where microvariability was detected.
