Pozanenko (IKI) report on behalf of larger collaboration:
We observed the field of GRB 160227A (Siegel et al., GCN 19098) with
HGB-500 telescope (0.5-m, f/2) of ISON-Kislovodsk observatory starting
on Feb. 27 (UT) 19:38:53, i.e. ~400 s after burst trigger. We obtained
several unfiltered images of 60 s exposure. We clearly detect the
afterglow of GRB 160227A (Siegel et al., GCN 19098; Gorbovskoy et al.,
GCN 19099; Andreev et al., GCN 19100). The afterglow brightness is
~18.0 magnitude at Feb. 27 (UT) 19:38:53.
