Li, University of California, Berkeley, on behalf of the \nKAIT GRB team, report: \n\nWe remotely observed GRB 051109A (Tagliaferri et al., GCN 4213)\nwith the 0.76-m Katzman Automatic Imaging Telescope (KAIT) at\nLick Observatory, and detected the afterglow (Rykoff et al., GCN 4211)\nin a series of unfiltered exposures. The following photometry\nare measured (calibrated to the USNO B1.0 catalog):\n\n           Start UT  Exp(s)    mag     err\n\n2005-11-09 02:25:48  120.0    18.67   0.04  \n2005-11-09 02:28:28  120.0    18.73   0.06\n2005-11-09 02:31:05  240.0    18.75   0.05\n2005-11-09 02:35:37  240.0    18.82   0.04\n2005-11-09 02:40:14  360.0    18.80   0.04\n2005-11-09 02:46:48  360.0    18.88   0.04\n2005-11-09 02:53:27  600.0    18.93   0.04\n\nWithin this period (74.5 to 106.1 minutes after the burst),\nthe afterglow declined with a power-law decay index of\n-0.62 +/- 0.07, consistent with the result resported by Mirabal\net al. (GCN 4215).",
