(ISTP), A. Pozanenko (IKI) report on behalf of larger GRB follow-up
collaboration:
We observed the field of the GRB 160327A (Racusin et al., GCN 19235)
with AZT-33IK telescope of Sayan observatory (Mondy) starting on March,
27 (UT) 13:48:49. We do not detect any source within enhanced Swift-XRT
position (Goad et al., GCN 19237). In particular we do not detect the
source reported in GCN 19236 and it could confirm the source (Zach
Golkhou et al., GCN 19236) is an afterglow of the GRB 160327A.
Preliminary photometry of the combined image is following
