We observed field of the SuperAGILE GRB 111211A (Lazzarotto et al. GCN
12666) with Zeiss-600 telescope of Mt.Terskol observatory in R filter
between Dec. 12 (UT) 23:09:07 -- Dec.13 00:55:27. We took several images
of 60 exposure under good weather conditions and mean seeing (FWHW) of about
1.8". We detect the source reported as candidate in afterglow (Kann et
al., GCN 12668; Kruehler et al., GCN 12675). A photometry is based on the
USNO-B1.0 1011-0183238 (10:12:26.16 +11:11:26.6) star assuming R = 14.41.
