Fox (Penn State) report on behalf of a larger collaboration:\n\nFurther analysis of the Gemini/GMOS spectrum of the nearby galaxy reported by\nCucchiara et al. (GCN 13245) revealed emission lines of Ha, OIII(5007/4959) and Hb\nat a common redshift of z=0.28.  At this redshift, the impact parameter of the afterglow\nis about 8kpc, which would be a rather large offset for a long-GRB, but certainly possible.\nIf the galaxy is the host, then the absence of absorption lines in the afterglow spectrum\nwould not be too surprising, given the weakness of expected lines in the observed\nwavelength range.  However, it would also make it one of the lowest\nredshift GRBs so far detected by Swift, and so an important target for further follow-up.",
