TITLE: GCN CIRCULAR NUMBER: 13251 SUBJECT: GRB 120422A: Gemini redshift of candidate host DATE: 12/04/22 20:18:05 GMT FROM: Nial Tanvir at U.Leicester N. R. Tanvir (U. Leicester), A. J. Levan (U. Warwick), A. Cucchiara (UCSC/UCO Lick) & D. B. Fox (Penn State) report on behalf of a larger collaboration: Further analysis of the Gemini/GMOS spectrum of the nearby galaxy reported by Cucchiara et al. (GCN 13245) revealed emission lines of Ha, OIII(5007/4959) and Hb at a common redshift of z=0.28. At this redshift, the impact parameter of the afterglow is about 8kpc, which would be a rather large offset for a long-GRB, but certainly possible. If the galaxy is the host, then the absence of absorption lines in the afterglow spectrum would not be too surprising, given the weakness of expected lines in the observed wavelength range. However, it would also make it one of the lowest redshift GRBs so far detected by Swift, and so an important target for further follow-up.
