OJ 287 is a blazar type active galaxy. The historical light curve shows outbursts occurring at quasi-regular intervals. These can be modeled by a secondary black hole interacting with the accretion disk of the primary black hole. We present results of wavelet analysis of the recent light curve of OJ 287, including the outbursts in 1994 and 1995.
