Brian Cameron report on behalf of\nthe Caltech-NRAO-Carnegie GRB Collaboration:\n\nWe have imaged the field of GRB050502 (GCN 3323) with the Large Format\nCamera (LFC) mounted on the Palomar 5-m Hale Telescope.  Observations\nconsisted of 2 x 600 s exposures in the Sloan r' filter.  At a mean\nepoch of ~ 11:30 3 May UT (33.3 hours after the burst), we find no\nemission at the afterglow position reported by Yost et al. (GCN 3322).\nOUr 3-sigma limiting magnitude, calculated by comparison with several\nGuide Star Catalog sources in the field, is approximately r' > 23.5",
