A. Pozanenko (IKI),  M. Ibrahimov (MAO), A. Volnova (SAI MSU), B. Satovski 
(Astrotel) report on behalf of  larger GRB  follow-up collaboration:

We observed  the field of INTEGRAL GRB 101112A (Gotz  et al., GCN 11396) 
with AZT-22 telescope of Maidanak observatory between Nov. 13 (UT) 
13:37:57 -- 14:05:56.Totally we obtained 6 images of 300 s exposure in R 
filter. The afterglow (Guidorzi et al. GCN 11397; A. de Ugarte Postigo et 
al. GCN 11398) is not visible on single images, and upper limit of the 
single image is R~20m at Nov.13 (UT) 13:40.
The result above is preliminary.

We thank Olga Ezhkova  for performing the observations and for support.
