S. Bradley Cenko, Derek B. Fox, and P. Brian Cameron report on behalf of
the Caltech-NRAO-Carnegie GRB Collaboration:
We have imaged the field of GRB050502 (GCN 3323) with the Large Format
Camera (LFC) mounted on the Palomar 5-m Hale Telescope. Observations
consisted of 2 x 600 s exposures in the Sloan r' filter. At a mean
epoch of ~ 11:30 4 May 2005 UT (57.3 hours after the burst), we find no
emission at the afterglow position reported by Yost et al. (GCN 3322).
Our 3-sigma limiting magnitude, calculated by comparison with several
Guide Star Catalog sources in the field, is approximately r' > 23.5.
