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=15.156 at JD=2459425.3107 with the degree of linear polarization of 33.5% (the previous night measurement was R=15.50 and polarization degree 27.5%). We plan to continue the monitoring of this object. The nightly updated light curve for this object can be found on our website.
