We observed field of the Swift GRB 111103B (Grupe et al. GCN 12519) with
Zeiss-600 telescope of Mt.Terskol observatory in R filter between Nov. 3

weather conditions and mean seeing (FWHW) of about 1.6". We do not detect
any source within enhanced XRT position (Goad et al., GCN 12525). A
photometry is based on the USNO B1.0 nearby stars.
