Tejero (GRANTECAN) report on behalf \nof a larger collaboration:\n\nWe observed the afterglow of GRB 161014A (Racusin et al., GCN 20035, \nMorita et al. GCN 20036, Guidorzi et al. GCN 20037, Xin et al. \nGCN 20038, Nakaoka et al. GCN 20039, D���Avanzo et al. GCN 20040, \nMazaeva et al. GCN 20042) with OSIRIS at the 10.4m GTC telescope on \nLa Palma (Spain). The observations started at 20:52 UT (with an average \nepoch at 8.8 hr after the burst) and consisted of 3 x 900 s spectra using \ngrism R1000B, which covers the spectral region between 3700 and 7800 AA \nat a resolution of R ~ 1000.\n\nThe spectrum has a low signal to noise ratio, but the preliminary reduction \nwith archive calibrations still reveals prominent features due to Ly-alpha, \nSiII, CII, SiIV, CIV, AlII, and AlIII at a common redshift of z=2.823, which \nwe identify as the redshift of the GRB.",
