We perform optical photometric and polarimetric monitoring of a sample of gamma-bright blazars using 0.4-m LX-200 telescope (St.Petersburg) and 0.7-m AZT-8 telescope (Crimean Astrophysical Observatory). We report that the blazar S41030+61 (z=1.409), associated with the gamma-ray source 3FGLJ1033.8+6051, reached R=14.6-14.8 in the nights of 2019 August 6-7, after a month of monotonic increase in brightness from R~18. R band light curve for S4 1030+61 can be seen on our web-page. The polarization degree during the phase of outburst is on the level of 15-35%. Current high activity state of this blazar deserves close attention in all wavelengths.
