GRB follow-up collaboration:
We observed the field of of the Swift GRB 160601A (Kocevski et al., GCN
19478) with AS-32 (0.7m) telescope of Abastumani Observatory starting on
June, 01 (UT) 19:07:28. We obtained several unfiltered images of the
field. In a combined image we detected both NOT sources (Malesani et
al., GCN 19485). Preliminary photometry of the optical afterglow (NOT
source #1, Schulze et al., GCN 19488) are following
