Flores (GEPI/Obs. de Paris)\nreport on behalf of a larger collaboration:\n\nWe observed the optical/NIR counterpart (e.g., De Pasquale et al. GCN\n14377, Gorosabel et al. GCN 14378) of GRB 130418A (De Pasquale et al.\nGCN 14377) with the VLT/X-shooter spectrograph.\n\nOur spectra cover the wavelength range 3000-25000 AA, and were taken\nstarting on 2013 Apr 18, 23:35:08 UT (4.57 hr after the GRB) for a\ntotal exposure of 20 min.\n\nWe identify absorption lines of CIV, FeII and MgII at a common redshift\nof z = 1.217 (see also de Ugarte Postigo et al., GCN 14380). The\ndoublet of CIV (1548, 1550) is also detected in a second absorption\nsystem at z = 1.218. No emission lines are evident in our spectrum.\n\nWe thank the VLT staff, in particular Henri Boffin, Dimitri Gadotti and\nAlex Correa, for the expert support in obtaining these data.",
