Leicester) and \nC.A. Alvarez Iglesias (IAC-ULL) report:\n\nWe have observed the afterglow of GRB 130418A (De Pasquale et al. GCN\n14377) with the 10.4m GTC telescope starting at 21:45 UT (2.75 hr after the\nburst). Observations consisted of 2x600s using the R1000B grating, with a \nresolution of R~1000 in the range 3600 - 7900 A.\n\nThe spectrum shows a high S/N trace, with very weak MgII features at a \nredshift of z = 1.218, which we identify as the redshift of the GRB.\n\n[GCN OPS NOTE(19apr13):  Per author's request, CAAI's affiliation\nwas changed from GTC to IAC-ULL.]",
