GRB050801.769: Unchanged decay slope J. P. U. Fynbo, B. L. Jensen, J. Hjorth, K. G. Woller, D. Watson, J. Sollerman (Niels Bohr Institute), P. Fouque (Obs-MiP, Toulouse), M. I. Andersen (Potsdam, AIP) report on behalf of the DARK Cosmology Centre: "We have obtained additional DK-1.5m R-band imaging (Aug 3.0 UT) of the optical afterglow (Rykoff et al. GCN#3726) of GRB050801.769 (Band et al. GCN#3725). Extending the fit from Fynbo et al. (GCN#3726) yields a smooth well-fitting power-law from t-t0=0.44h to 29.5h, with an R-band decay slope of -1.31 +- 0.04. The lightcurve is shown at: http://www.astro.ku.dk/~brian_j/grb/grb050801.769/ "
