We report on the results of R band observations of the error box of thegamma-ray burst of August 28, 1997, made between 4 hours and 8 days after thisburst occurred. No counterpart was found varying by more than 0.2 magnitudesdown to R = 23.8. We discuss the consequences of this non-detection forrelativistic blast wave models of gamma-ray bursts, and the possible effect ofredshift on the relation between optical absorption and the low-energy cut offin the X-ray afterglow spectrum.Comment: 15 pages including 3 figures, LaTeX, accepted by ApJL, Nov. 13, 199
