TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3356 SUBJECT: GRB050502: P200 Observations (Correction) DATE: 05/05/05 00:39:15 GMT FROM: S. Bradley Cenko at Caltech 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 3 May UT (33.3 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
