report on behalf of a larger collaboration:

We carried out BVRI-band observations of the Swift GRB 100816A  (Oates  
et al., GCNC 11102) with the 1.23m Calar Alto telescope. The optical  
afterglow (Oates et al., GCNC 11102; Antonelli et al., GCNC 11104) is  
well detected in BVRI with a preliminary magnitude of I~19.9 on Aug  
16.0492 UT (~33 min post burst), calibrated using USNO-B1.0 field stars.
