E. Berger (Harvard) and M. Rauch (Carnegie) report:
"We obtained spectroscopic observations of the optical afterglow of GRB
081121 (GCNs 8536,8537) with the LDSS3 spectrograph on the Magellan/Clay
6.5-m telescope starting on 2008 Nov 22.16 UT. The spectra cover the
wavelength range 3800-6500A. We detect Ly-alpha absorption, as well as
aborption features corresponding to SiII, CII, SiIV, CIV, FeII, and AlII
at a redshift of z=2.512, which we consider the redshift of the burst.
Further analysis is in progress."
