Fox (Penn State) report on \nbehalf of a larger collaboration:\n\n\"Using GMOS on the Gemini-south telescope we obtained a 2400 spectrum of \nan apparent galaxy located within the error circle of XRT source #1 (GCN \n6095).  This is the only X-ray source which exhibits signs of fading and \nis the nearest to the BAT error circle of this burst (GCN 6087).  We find \nthat the redshift of the galaxy is z=0.314 based on the detection of CaII \nH&K, as well as [OII] and [OIII] emission lines.  At this redshift, the \nisotropic-equivalent energy of the burst is 2.6e48 erg.\"",
