Paris) report on behalf of the X-shooter \nGTO GRB collaboration,\n\nWe observed the afterglow of GRB121201A (Yeshov et al., GCN 14025, Kruehler \net al. GCN 14031) using the X-shooter spectrograph on the VLT (Paranal Observatory, \nChile). Observations consisted of 4x1200s exposures in the UVB and VIS arms and \n8x600s exposures in the NIR, and started on 2 December 1:17 UT (12.87 hr after the \nburst).\n\nIn a preliminary reduction we detect Ly-alpha in emission as well as several \nabsorption features (SiIV, CIV, AlII, AlIII) at a common redshift of z=3.385, which we \nidentify as the redshift of the GRB.\n\nWe acknowledge the excellent support of the VLT staff, in particular G. Carraro.",
