Tessicini (INAF-TNG) report on behalf of the CIBO\ncollaboration:\n\n\nWe observed the optical afterglow (Xu et al., GCN 15304; Malesani et  \nal., GCN 15305; Kopac et al., GCN 15306) of the possible short GRB  \n131004A (Hagen et al., GCN 15303) using DOLORES/LR-B (wavelength  \nrange: 3000-8000 AA) on the 4-m TNG Telescope at Canary islands. We  \nobtain a 1800 s spectrum starting at 2013-10-04 23:00:38 UT, i.e.,  \n1.33 hr from the burst.\n\nA preliminary reduction reveals weak emission lines from [O II],  \nH-gamma and H-delta at a common redshift of 0.71.\n\nWe thus confirm the redshift reported by Chornock et al. (GCN 15307).\n\n----------------------------------------------------------------\nThis message was sent using IMP, the Internet Messaging Program.",
