GCN Circ. 13105)\non March 26, from 01:34:07 UT, corresponding to\n13.6 minutes after the BAT trigger time.\nWithin the XRT error circle we clearly detect the\noptical afterglow (Klotz et al. GCN Circ. 13107,\n13108; LaCluyze et al. GCN Circ 13109) with the\nSDSS riz filters at the following position\n\n18:15:37.13   +69:15:35.7   (J2000)\n\nuncertainty of 0.3\". We estimate the magnitude\nof the afterglow as follows:\n\nMid time from    Exp     Filter    Magnitude\nGRB (min)        (s)\n---------------------------------------------\n14.1             3x10    r        19.1 +- 0.2\n44.8             120     r        19.6 +- 0.1\n---------------------------------------------\n\nMagnitudes are calibrated against nearby USNOB-1\nstars.",
