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.
