larger 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 July, 
03 (UT) 19:07:28. We obtained several unfiltered images of the field. 
Within XRT error circle (D'Ai et al., GCN 19641) we do not detected 
optical afterglow (Klotz et al., GCN 19622; Sokolov et al., GCN  19623). 
Preliminary photometry  of the field  is following
