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
