Smith (Gemini) report on behalf of a larger collaboration:\n\nWe observed the afterglow of GRB 130505A (Cannizzo et al. GCN 14563)\nwith the GMOS-N spectrograph on Gemini-N, beginning approximately 60 min\nafter the BAT trigger.\n\nIn our provisional reduction we detect numerous absorption lines, including\nLyman alpha, SiII/SiII*1260, SiII*1264, OI1302, SiII/OI*1304, SiII*1309,\nCII/CII* 1334/1335, SiIV1394/1403, SiII 1527, SiII* 1533, CIV 1548/1551,\nFeII 1608, AlII 1671 and AlIII 1855/1863 at a common redshift of z=2.27.\n\nThe presence of fine structure lines, in particular, confirms this to be the\nredshift of this burst.",
