Optical microvariability in type 2 quasars

The AGN unified scenario suggests that the type 2 quasars are the obscured counterparts of type 1 quasars where the difference is caused only by the orientation of the object. Optical microvari ability is supposed to arise from the regions which are closer to the supermassive black hole at the center of the AGN. The search for microvariability is an important test for the AGN unified scenario. We present first results from the microvariability campaign carried out at San Pedro Martit observatory. We have targeted three brightest (V mag < 17) type 2 quasars from SDSS. Using analysis of variance (ANOVA), we have detected significant microvariability events in two out of three type 2 quasars we have observe
