Abstract

We present a study on the optical flux microvariability for a sample of gamma-ray blazars observed from 2006 to 2007: PKS 0048-090, 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. We detected some low amplitude microvariability and internight varibility for the whole sample in both V and R filters, as a result of a statistical analysis of the light curves. Furthermore, we found it possible for this behaviour to be produced after a slight oscillation of the jet's direction - i.e. a swinging jet scenario.
