A.Pozanenko (IKI) on behalf of larger GRB follow up collaboration report:
We are continuing observations of the Swift GRB 100901A (Immler et al., GCN
11159) with the Z-600 telescope of Mt.Terskol observatory in R-filter. In
combined images we still detect afterglow (Immler et al., GCN 11159). The
photometry is based on several reference stars of SDSS DR7 and Lupton
transformation griz -> R used in our previous reports (GCNs 11191, 11200):
