(IKI) report on behalf of larger GRB follow-up collaboration:
We observed the field of GRB 161014A (Racusin et al., GCN 20035) with
Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory.
We obtained several images in R filter starting on Oct. 14 (UT)
13:48:35. We detected the afterglow of GRB 161014A (Morita et al., GCN
20036; Guidorzi et al., GCN 20037; Xin et al., GCN 20038). Preliminary
photometry of of combined the first observational set is following
