Reichart (Caltech) report:\n\nOn March 5, we observed the entire 50 arcmin diameter error circle of \nGRB 020305 (HETE 1939; GCN 1262) with the automated 8\" Pisgah Survey Telescope \nat PARI (Pisgah Astronomical Research Institute) in Rosman, North Carolina.  \nObservations began 15.8 hours after the burst.  Visual comparison with the DSS \nrevealed no new sources at that time.\n\nAt the location of the candidate afterglow (GCN 1267), we are partially \ncontaminated by light from a nearby, bright (I = 14.7 +- 0.1 mag) star.  \nConsequently, we reimaged the field on March 15.  Comparison of aperture \nphotometry between the two epochs allows us to place the following limits at \nthe location of the candidate afterglow on March 5:  I > 17.6 mag (1 sigma), \nI > 16.8 mag (2 sigma), and I > 16.4 (3 sigma).",
