report:

 We observed the field of the Swift GRB 120116A (Melandri et al., GCN
12834Not found
 
 
) with ORI-40 telescope of Kitab ISON observatory on Jan. 16
 starting (UT) 18:12:48, i.e. ~6 min after burst trigger. We obtained
several unfiltered images with exposure of 60 seconds. On the stacked
image we do not detect any source within the enhanced XRT error box
(Goad et al., GCN 12846Not found
 
 
). The photometry is based on nearby reference
stars of USNO-B1.0
 (R2 magnitudes):
