GRB follow-up collaboration:
We observed the field of the INTEGRAL GRB 160629A (Gotz et al., GCN 19621)
with AS-32 (0.7m) telescope of Abastumani Observatory on June, 01 (UT)
19:07:28. We obtained several unfiltered images of the field. Within XRT
error circle (D'Ai et al., GCN 19641) we detected optical afterglow (Klotz
et al., GCN 19622; Sokolov et al., GCN 19623) on July 1, and obtained upper
limit on June 30. Preliminary photometry of the optical afterglow is
