larger GRB follow up collaboration report:

We observed the error box of Swift GRB 081128 (Margutti  et al, GCN 8571) 
in I band on Nov. 28 between (UT) 20:20:28 - 20:31:16 with AZT-8 telescope 
of CrAO. Inside the refined XRT error box (Evans et al. GCN 8573) we do 
not detect the source reported as possible afterglow (Wang et al, GCN 
8572; Lin et al, GCN 8575; Andreev et al, GCN 8576; Guidorzi et al, GCN 
8577). The photometry of the combined image is following:
