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

The photometry is based on nearby SDSS star J073110.29+170129.9
assuming R_Lupton = 16.132.
