Krzeminski (Las Campanas\nObservatory) report:\n\n\"We imaged the 4-arcmin radius error circle of GRB 050202 (GCN 3005) with\nthe Swope 40-inch telescope at Las Campanas Observatory on February 2.40\nUT (6 hours after the burst) in R-band.  Observations were taken at high\nairmass and with a high sky background (as the Sun was rising) and as a\nresult reach a limit of only R~16 mag.  To this limit we do not find any\nobjects within or near the error circle which are not present in the DSS.  \nWe note that with a time delay of six hours, this limit is of similar\nquality to any of the limits obtained to date (Hurley et al. 2002, ApJ,\n567, 447)\"\n\nThis message may be cited."
