Resumen:
Aims. We aim at investigating the time-behaviour of a sample of gamma-ray blazars. We present the results from a 13 monthlongoptical photometry monitoring campaign of the blazars PKS 0048−097, PKS 0754+100, [HB89] 0827+243, PKS 0851+202,PKS 1253−055, PKS 1510−089, PKS 1749+096, PKS 2230+114 and PKS 2251+158.Methods. We analyse the variability of each object, focusing on different time-scales (long term, short term, and microvariability), inan attempt to achieve a statistical comparison of the results.Results. After applying a geometric model to explain the variability results, we found that it is possible that a slight change in thedirection of the jet generates the variations detected in some objects during this campaign.
