We perform optical photometric and polarimetric monitoring of a sample of gamma-bright blazars using 0.7-m AZT-8 telescope (Crimean Astrophysical Observatory), within the frames of GASP/WEBT project. We report that the blazar B21420+32 (z=0.681) is active in optical, reaching R=16.13 at JD=2459792.3281 with the degree of linear polarization of 22.5% (compared to R=17.35 at JD=2459789.3055). We plan to continue the monitoring of this object. The nightly updated light curve for this object can be found on our website.
