GCN 8186)\n at 16:51:15.5 UT, 3.6 h after the Swift triggger. We do not detect the\n afterglow reported by Holland et al. (GCN 8198) and Afonso et al. (GCN\n 8194). Our first 120s exposure has a limiting magnitude of 16.9, while\n a stacked sequence of 10 120s images, with an exposure mid-time of 3.8\n hrs after the trigger, results in a limiting magnitude of 18.4.\n Unfiltered magnitudes are transformed to R-band by comparison with the\n USNO-B1 catalog.",
