The observations were started at \n2011-02-13 17:18:32 (UT) and stopped at 2011-02-13 18:24:28 (UT).\nThree unfiltered and three photometric R observations with 600s exposure\ntimes were made. The afterglow was detected at following position \nRA 02:51:51.41 and DEC +49:16:23.0.\n\nThe following magnitudes were obtained from the observations using \nNOMAD1 1392-0071642 (R=15.230) as the comparison:\n\nTmid(s)+T0    Filter     Exp (sec)     Mag         Mag err      Limit\n44163             unfilt     3x600            19.1       0.2             20.3\n46231             Rc        3x600            19.2       0.3             20.1",
