Rauch (Carnegie) report:\n\n\"We obtained spectroscopic observations of the optical afterglow of GRB\n081121 (GCNs 8536,8537) with the LDSS3 spectrograph on the Magellan/Clay\n6.5-m telescope starting on 2008 Nov 22.16 UT.  The spectra cover the\nwavelength range 3800-6500A.  We detect Ly-alpha absorption, as well as\naborption features corresponding to SiII, CII, SiIV, CIV, FeII, and AlII\nat a redshift of z=2.512, which we consider the redshift of the burst.\nFurther analysis is in progress.\"",
