Abstract: We present optical data of the quasar 1156+295 (4C 29.45) taken in the last four years at the Torino Astronomical Observatory with the 1.05 meter REOSC telescope. Large-amplitude variations characterize the source light curve; in particular, during the last observational season an optical outburst was detected, the R magnitude reaching 13.68 on March 17, 1998. A CGRO pointing was obtained as a ToO: the comparison between the optical and gamma-ray emissions will provide constraints for the interpretation of the high-energy emission mechanisms.
