Price\n(IfA/Hawaii) report on behalf of a larger collaboration:\n\nWe observed the field of the short-hard GRB061210 (Cannizzo et al., GCN\n5904) with the Gemini Multi-Object Spectrograph in imaging mode mounted\non the Gemini North telescope.  Our first set of observations was taken\nin r' at a mean epoch of 14:27 Dec. 10 UT (2.1 hours after the burst)\nand covers ~ 90% of the refined BAT error circle (Palmer et al., GCN\n5905).  Contamination from the nearby moon significantly affected the\nsensitivity of these images.\n\nA second r' reference epoch was taken the following evening, at a mean\nepoch of 13:54 Dec. 11 UT (25.6 hours after the burst).  Digital image\nsubtraction using the ISIS software package (Alard & Lupton 1998, ApJ,\nv. 503, p. 325) revealed no variable object anywhere in the field.  We\nplace a limit of r' > 23.5 mag for any isolated point-source afterglow\nemission at the time of the first epoch.",
