Pozanenko (IKI) on behalf of\nlarger GRB follow up collaboration report:\nWe observed the field of the Swift GRB 121128A (Oates et al., GCN 14007)\nwith AZT-33IK telescope of Sayan observatory (Mondy). We took several\nimages in R-filter of 60 s exposure on Nov. 28, between (UT) 10:27:30 -\n13:43:09 under favorable weather conditions. We detected optical afterglow\n(Oates et al., GCN 14007; Japelj et al., GCN 14008) in stacked images. A\nphotometry of some stacked image in the beginning of our observations and\nfinal stacked image is based on nearby USNO-B1.0 stars:\nt_start, T0+ (mid), filter, exp., OT, err\n(UT)     d                           s\n\n10:46:51 0.24047 R     10x60 19.95 +/- 0.06\n13:00:21 0.34123 R     49x40 20.58 +/- 0.07\n\nThe photometry is still preliminary.",
