GCN Circular 12764
D. Xu (WIS/NAOC), J.P.U. Fynbo (DARK), J. McCormac (Queen's Univ. Belfast), and P. Jakobsson (Univ. Iceland) report on behalf of a larger collaboration: We secured spectroscopy of the afterglow of GRB 111228A (Ukwatta et al., GCN 12737) with the 2.5m Nordic Optical Telescope (NOT) equipped with the ALFOSC optical camera. Observations started immediately after the 600s R-band photometry in Xu et al. (GCN 12750). The NOT spectrum covers 2750-9000A and shows clear absorption lines of MgII2803 and CaH&K, at a common redshift of z=0.713. Further observations are planned.
