Pozanenko (IKI) \nreport on behalf of  larger GRB  follow-up collaboration:\n\nWe observed the afterglow of the Swift GRB 100111A (Vetere et al. GCN 10317) \nwith AZT-22 (1.5 m) telescope of Maidanak observatory (MAO) in R band on \nJan. 12 (UT) (00:44 - 01:32) under good weather conditions with mean seeing \nof about 0.8 arcsec. The optical afterglow (Vetere et al. GCN 10317) is \nclearly detected in enhanced XRT error\ncircle (Beardmore et al. GCN 10321). A photometry of combined image is based \non several SDSS DR7 field stars:\n\nT0+     Filter  Exp.    Mag.
