Pozanenko (IKI) report on behalf of \nlarger GRB  follow-up collaboration:\n\nWe observed  the field of the Swift GRB 110106A (Mangano et al., GCN 11520) \nwith AZT-11 telescope of CrAO starting on Jan. 06 (UT) 16:26. In the\nenhanced Swift-XRT position  (Osborne al., GCN  11526) we do not detect \noptical afterglow candidate (Malesani et al., GCN 11524) up to R=21.9. We \nclearly detect the nearby galaxy outside the error circle (Malesani et al., \nGCN 11524, Piranomonte et al., GCN 11530, Gorbovskoy et al., GCN 11542). The \nphotometry is based on the USNO B1.0 star 1541-0130790  (05:17:11.42 \n+64:10:11.0) assuming R=17.81.
