Resumen:
We report here the first results of a long term optical (V , R) monitoring program of blazars that includes 3 well-known objects: 3C279 (1253−055), CTA102 (2230+114) and 3C454.3 (2251+158). The observations were obtained with the 1.52m Spanish telescope at the Calar Alto Observatory during 2006−2007. Although no significant intra-night variations were detected in any of the objects, we found inter-day variations with amplitudes of ~ 0.15 mag in these gamma-ray blazars.
