We observed the field of the GRB 160910A (Veres  et al., GCN 19901; Racusin 
et al., GCN 19902) with  AZT-33IK telescope of Sayan observatory (Mondy) 
starting on Sep., 12 (UT) 14:02:46. We obtained several images in R-filter. 
We  clearly detected optical afterglow (Ugarte Postigo et al., GCN 19907; 
Malesani et al., GCN  19908; Lipunov et al., GCN  19914). Preliminary 
photometry  of the afterglow is following
