Pozanenko(IKI)\nreport on behalf of larger GRB follow-up collaboration:\n\nWe observed the field of the Swift GRB 131127A (Markwardt et al., GCN\n15516)  with AZT-33IK telescope of Sayan observatory (Mondy) starting Nov.,\n27 (UT) 10:40:06. We obtained  several images in R-filter with exposure of\n30 and 60 seconds. Within the XRT circle  (Markwardt et al., GCN 15516)  we\ndid not detect any optical object.\n\nThe details of the photometry are the following:\n\nUT start,      t-T0           Filter    Exp.
