GCN #2858) in the\nR-band using the MDM 1.3m telescope under conditions of poor seeing.\nA total of 50 minutes of exposure centered at Dec. 19, 05:03 UT, or\n13.3 hours after the burst showed a faint object of R = 22.15 +/- 0.25\nat the position of the OT reported by Torii et al (GCN #2860),\nGorosabel et al. (GCN #2861), and Greco et al. (GCN #2863). \n\nWe use for comparison the USNO B1.0 star 1613-0027268 located at\nR.A. = 01h39m04s.17, Decl. = +71o21'06\".0 (J2000) for which\nHenden (GCN #2869) gives Rc = 16.65.\n\nWe note that there is considerable Galactic extinction in this direction, \nE(B-V)=0.63 corresponding to A_R=1.67 (Schlegel et al. 1998).\"\n\nAn image is posted at:\n\nhttp://www.astro.columbia.edu/~jules/grb/041218/\n\nThis message can be cited.",
