(IKI) on behalf of larger GRB follow up collaboration �report:

We observed the field of the Swift GRB 120116A (Melandri et al., GCN
12834) with AZT-33IK telescope of Sayan observatory (Mondy) on Jan, 16
between (UT) 18:49:24 - 19:20:20, i.e. starting 40 minutes after the
trigger. We took several series of 60 s exposures in R-filter. Within
the XRT error circle (Melandri et al., GCN 12834) �we do not detect
any source, in particular we do not detect the source reported by
Levan and Tanvir (GCN 12843). The photometry is based on the USNO-B1.0
1239-0020213 star (RA=01 05 04.50, Dec=+33 55 37.7) assuming R2=16.36.
