report on behalf of a larger collaboration:
We observed the counterpart of GRB 121128A (Oates et al. GCN 14007;
Japelj et al. GCN 14008) with the GMOS-N spectrograph at Gemini-North,
beginning at Nov 28 2012 06:06 UT, approximately 1hr post-burst.
The afterglow is well detected and our provisional reduction shows a
series of absorption lines of AlII, FeII, CIV, SiII, SiIV with a common
redshift of z=2.20.
