Molotov (KIAM), report on behalf of larger \nGRB follow-up collaboration:\n\nWe observed the field of the INTEGRAL GRB 160629A (Gotz et al., GCN 19621) \nwith AS-32 (0.7m) telescope of Abastumani Observatory  on June, 01 (UT) \n19:07:28. We obtained several unfiltered images of the field. Within XRT \nerror circle (D'Ai et al., GCN 19641) we detected optical afterglow (Klotz \net al., GCN 19622; Sokolov et al., GCN  19623) on July 1, and obtained upper \nlimit on June 30. Preliminary photometry  of the optical afterglow  is \nfollowing\n\nDate        UT start           t-T0          Filter  Exp.
