We present the R_c band light curve of the optical transient (OT) associatedwith GRB970228, based on re-evaluation of existing photometry. Data obtaineduntil April 1997 suggested a slowing down of the decay of the opticalbrightness. However, the HST observations in September 1997 show that the lightcurve of the point source is well represented by a single power law, with a``dip'', about a week after the burst occured. The exponent of the power lawdecay is $\alpha$ = --1.10 $\pm$ 0.04. As the point source weakened it alsobecame redder.Comment: 5 pages, latex, to appear in Gamma-Ray Bursts, 4-th Huntsville  Symposium, eds Meegan, Preece, Koshu
