GCN 10256;\nde Ugarte Postigo et al. GCN 10255) with the GMOS-N spectrograph on Gemini\nNorth, beginning at 11:17 UT on December 8. We use the R400 grism.\nThe resulting spectrum covers the wavelength range 4000-8400 A and shows \nclear absorption lines of the MgII doublet (2796,2803), MgI (2853), FeI \n(2967), FeII (2586,2600) and MnII (2576,2594,2606) at a common redshift\nof z = 1.063.\n\nWe thank the Gemini-N staff, in particular K. Chiboucas, for\nperforming this observation.",
