Gomez-Velarde (ULL-IAC, GTC) report on \nbehalf of a larger collaboration:\n\nWe have observed the afterglow of the Fermi GRB140801A (Gorbovskoy et al. \nGCN 16653, Xu et al. GCN 16655) with the 10.4m GTC (+OSIRIS). Spectroscopic \nobservations began at 3:35 UT (8.59 hr after the burst). The first 900 s spectrum \nwas obtained with the R1000B grism, and covered the range between 3630 and \n7500 A, at a resolution of ~1000.\n\nWe detect a strong continuum with absorption features that correspond to NiII, \nMnII, FeII, MgII, and MgI at a common redshift of z=1.320, which we identify as the \nredshift of the GRB.\n\nFurther spectroscopic observations are ongoing.",
