(IKI) report on behalf of larger GRB follow-up collaboration:
We observed the field of GRB 150910A (Pagani et al., GCN 18264) with
Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory on
Sep. 11 and Sep. 12. We obtained several images in R filter. The
afterglow (Pagani et al., GCN 18264; Zheng & Filippenko, GCN 18265) is
clearly visible in a combined image on Sep. 11 and on Sep. 12 we
obtained upper limit. The photometry of the combined images are following
