Singer (Caltech) report\non behalf of a larger collaboration:\n\nWe imaged the field of the Fermi GBM (Von Kienlin et al., GCN 14530) and\nLAT (Kocevski et al., GCN 14532) GRB130502B with the robotic Palomar 60\ninch telescope.  Observations began at 03:34 UT on 3 May 2013 (~ 0.82 d\nafter the GBM trigger) and were obtained under poor seeing conditions.  We\ndetect no significant emission at the position of the candidate X-ray\nafterglow (Melandri et al., GCN 14540).  Using nearby point sources from\nthe USNO-B1 catalog for reference, we measure an upper limit of r' > 20.4\nmag at this time.",
