摘要：

New data from the optical monitoring of gamma-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 1.05 m REOSC telescope equipped with a 1242 x 1152 pixel 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 gamma-ray band will contribute to better understand the mechanism of the gamma-ray emission. The finally show intranight light curves of 3C 66A and OJ 287;, where microvariability was detected.
