TITLE: GCN CIRCULAR NUMBER: 19241 SUBJECT: GRB 160327A: Mondy optical upper limit DATE: 16/03/28 15:43:01 GMT FROM: Alexei Pozanenko at IKI, Moscow E. Mazaeva (IKI), A. Volnova (IKI), E. Klunko (ISTP), I. Korobtsev (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 Date UT start t-T0 Filter Exp. UpperLimit (3 sigma) (mid, days) (s) 2016-03-27 13:48:49 0.20675 R 25*120 23.0 Photometry is based on nearby SDSS-DR9 stars, Lupton transformations into R.
