From 2013/02 18.13 to 2013/02\n18.21UTC (73.5 to 75.5 hours after the BAT trigger), we obtained a\ntotal of 1.40\nhours exposure in the r' and i' bands and 0.53 hours of exposure in the Z,\nY, J, and H bands.\n\nIn comparison with USNO-B1 and 2MASS, we derive the following AB\nmagnitudes, not corrected for Galactic extinction in the direction of the\nGRB, for the afterglow:\n\n  r'  21.92 +/- 0.09\n  i'  20.92 +/- 0.07\n  Z   20.21 +/- 0.12\n  Y   20.38 +/- 0.15\n  J   20.37 +/- 0.13\n  H   19.59 +/- 0.11\n\nWe thank the staff of the Observatorio Astronómico Nacional in San Pedro\nMártir.",
