To all GCN Sites: #-03 For the recent GRB on 28 Aug 97, Shri Kulkarni et al. report the following: GRB 970828 S. C. Odewahn, S. G. Djorgovski, S. R. Kulkarni (Caltech) and D. A. Frail (NRAO) report: "We have examined CCD images of the field of GRB 970828 obtained at the Palomar 200-inch Hale telescope by T. Herter, F. Fang and O. Pevunova on August 29, UT and compared them to images obtained by Steidel, Adelberger and Kellog on August 30, 31 and September 1 UT (and reported in IAUC 6370). Our preliminary analyis shows no objects brighter than about R magnitude of 24.5 within the ASCA/RXTE/IPN error-box (see IAUC 6728, 6731), which changed significantly by more than 0.2 magnitudes per day within this time interval. This places severe limit on the peak brightness of any possible optical transient associated with this burst."
