Abstract: The results of the optical monitoring of quasars in Tuorla Observatory between September 1995 and May 1997 are presented. Total number of monitored objects were 28. Some of the objects were targets of the simultaneous multifrequency monitoring campaigns (as RXTE or EGRET) and some other objects were monitored as a part of the OJ-94 project. During our monitoring campaign we measured brightest V-band magnitudes ever in objects ON 231 (W Comae) and 3C 66A. There were also some quite strong outburst also in several other sources too (like S5 0716+714, MK 421, CTA 102 ect.). Typical for almost all objects is fast flickering and 0.2-0.4 mag flares, there are also some evidences on short time periodicity in few objects, not yet confirmed.
