larger GRB follow-up collaboration:
We observed the field of the INTEGRAL GRB 160629A (Gotz et al., GCN
19621) with AZT-33IK telescope of Sayan observatory (Mondy) starting on
July, 01 (UT) 18:39:36. We obtained several images in R-filter. Within
XRT error circle (D'Ai et al., GCN 19641) we detected optical afterglow
(Klotz et al., GCN 19622; Sokolov et al., GCN 19623). Preliminary
photometry of the field is following
