A. Volnova (IKI), E. Chornaya (UAFO), E. Mazaeva (IKI), A. Matkin
(UAFO, ISON), I. Molotov (KIAM), A. Pozanenko (IKI) report on behalf
of larger GRB follow-up collaboration:
We observed the field of the GRB 160314A (D'Elia et al., GCN 19182)
with SANTEL-650 (0.65m) telescope of UAFO/ISON-Ussuriysk observatory
starting on March, 14 (UT) 11:32:51. We obtained series of unfiltered
images of 30 s exposure. We do not detect any optical afterglow within
XRT error circle (D'Elia et al., GCN 19182). Photometry of a combined
image of few first frames is following
Date UT start t-T0 Filter Exp. OT U_limit (3sigma)
(mid, days) (s)
2016-03-14 11:32:51 0.01728 none 3*30 n/d 18.7
The photometry is based on nearby SDSS star J073110.29+170129.9
assuming R_Lupton = 16.132.
