Miller (Gemini) report:\n\nWe observed the afterglow of GRB 140423A (Sonbas et al. GCN 16142;\nElenin et al. GCN 16143; Kaur et al. GCN 16144; Ferrante et al. GCN 16145;\nChester et al. GCN 16147) with the GMOS-N spectrograph on Gemini-N.\nObservations began at 10:25 UT, approximately 1.9 hr post burst.\n\nThe spectra show absorption lines due to Ly-alpha, SiII (1251/1254),\nSiII* (1265), OI (1302), SiII (1304), CII (1334), SiIV (1394/1403), \nSiII (1527), CIV (1548/1551) at a common redshift of z=3.26, which \nwe infer is the redshift of the GRB.",
