Warwick) report on \nbehalf of a larger collaboration:\n\nWe observed the afterglow of GRB 081222 with Gemini-North/GMOS Nod & \nShuffle spectroscopy beginning 22 Dec 2008 06:38 UT, approximately 105 \nminutes post-burst. From absorption lines of SiII, CIV, and FeII, we \nconfirm the redshift reported in GCN 8713 (Cucchiara et al.) of z=2.77. \nWe also find tentative evidence for a lower redshift system at z=2.74.\n\nWe thank the Gemini staff, in particular Ricardo Schiavon, for \nconducting these observations.",
