Pozanenko (IKI) report on behalf of larger GRB follow-up \ncollaboration:\n\nWe observed the field of Swift GRB 151022A (D'Avanzo et al., GCN 18436) \nwith AZT-33IK telescope of Sayan observatory (Mondy) starting on Oct. 22 \n(UT) 15:05:04. We obtained several images in R-filter of 30 s exposure. \n    Within XRT error circle (Evans, GCN 18438)  we do not detect any \noptical source in any single image. Upper limit (3 sigma) of a single \nimage is R ~ 19.4m. Photometry is based on nearly USNO-B1.0 (R2) stars.",
