We observed the field of the GRB 161007A (D'Elia et al., GCN 20008) with
AS-32 (0.7m) telescope of Abastumani Observatory on October, 07 (UT)
22:14:13. We obtained several unfiltered images of the field. Within XRT
error circle (Goad et al., GCN 20013) we do not detected optical
afterglow candidate (de Ugarte Postigo et al., GCN 20014). Preliminary
photometry of the field is following
