Fox (Penn State)\nreport on behalf of the Caltech-NRAO-Carnegie Collaboration:\n\nWe have imaged the field of GRB 060111(a) (Zane et al., GCN 4479) with the\nautomated Palomar 60-inch telescope.  Observations consisted of 9 x 180 s\nexposures in the Kron R-band taken at a mean epoch of 13:19:49 11 January\nUT (~ 8.9 hours after the burst trigger).\n\nWe find no sources in the revised XRT error circle (Goad et al., GCN 4481)\nor at the location of the proposed UVOT counterpart (Blustin, Zane, and\nRosen, GCN 4482).  The limiting magnitude of our observations, calculated\nwith respect to several Guide Star Catalog sources in the field, is R >\n20.5.",
