GCN 11087) with the SDSS\nr- and i-filters during the commissioning run of CQUEAN (the Camera for\nQUasars in the Early uNiverse) on the 2.1m telescope at the McDonald\nObservatory. The observation started at 2010 August 14, 08:57:54 UT,\nabout 5 hours after the BAT trigger.\n\n  A series of 180 secs exposures were taken, and we confirm the afterglow\nat the location reported by Schaefer et al. (GCN 11086) and Gorosabel et \nal.(GCN 11090). A preliminary photometry from a single frame with the\nmid-point time of 09:00:24 UT is r ~ 19.10 +- 0.03 AB mag (subject to \nsystematic error in the zero point determination), consistent with the \nvalue reported by Filgas et al. (GCN 11091). The photometric calibration \nis based on a standard star observation on the same night (BD+17 4708).\n\n   We thank the staffs of the McDonalnd Observatory, Peter S. Odoms and \nJohn Kuehne for their assistance of the CQUEAN commissioning run.",
