Ten 60 s\nobservations were carried out in the R filter starting\n2011-12-08 at 17:04:45 UT (~ 31 ks after the GRB trigger).\nThis observation is in temporal coincidence with the Swift\nXRT TOO observation which spanned from 24.3 ks to 34.9 ks\n(Wolf et al., GCN 12631).\n\nIn the stacked R band image, we do not detect an optical\nafterglow at the XRT location. Our upper-limit based on the\nobservation is given below.\n\nTime after trigger       Exposure (s)   Filter     Magnitude\n  8.61 hours             600               R         > 19",
