report on behalf of larger GRB follow-up collaboration:
We observed the field of the GRB 160910A (Veres et al., GCN 19901;
Racusin et al., GCN 19902) with Zeiss-1000 (East) 1-m telescope of Tien
Shan Astronomical Observatory. We obtained several images in R filter
starting on Sep., 12 and Sep., 15. 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

Photometry is based on nearby SDSS-DR9 stars used in GCN 19919 (Mazaeva
et al.).
