Resumen: In this work, results from an optical flux monitoring campaign (V and R filters) of northern hemisphere blazars are presented. The observations were made using the 1.52m telescope at the Calar Alto Observatory, Spain, during 2006 and 2007. A total of 10 objects were followed in different observing runs. Significant intranight (hour-based scale) variability was not detected in any object of this sample. However, internight (day-based scale) variability was indeed detected in some of the sources.
