Fox (Penn\nState) report on behalf of a larger collaboration:\n\nWe have imaged the field of GRB 051006 (Norris et al., GCN 4061) with\nthe automated Palomar 60-inch telescope.  Observations consisted of 10 x\n150 s R-band images taken at a mean epoch of approximately 9:20, 7\nOctober UT (12.9 hours after the burst).  In a co-addition of our\nimages, we find no new sources inside the refined XRT error circle\n(Capalbi et al., GCN 4066).  Using several Guide Star Catalog sources in\nthe field, we estimate our limiting magnitude to be R > 21.0.  \n\nIn particular, we do not detect source #3 identified by de Ugarte et al.\n(GCN 4064) to the magnitude limit quoted above.",
