GRB follow-up collaboration:
We observed the field of Swift and Fermi GRB 160223A (Markwardt et
al., GCN 19057; Veres et al., GCN 19064) with AS-32 (0.7m) telescope of
Abastumani Observatory starting on Feb. 23 (UT) 23:51:22. We obtained
several unfiltered images of the field. We do not detect afterglow
candidate (Bolmer et al., GCN 19058) down to 20.4m. A preliminary
photometry of the field is following
