Subject
GRB 120326A: GTC redshift

J. C. Tello, R. S�nchez-Ram�rez, J. Gorosabel, A. J. Castro-Tirado (IAA-CSIC Granada), M. A. Rivero, G. G�mez-Velarde (GTC La Palma) and A. Klotz (IRAP-CNRS-OMP), on behalf of a larger collaboration, report:

"Following the detection of the optical afterglow to GRB 120326A (Siegel et al. GCNC 13105, Klotz et al. GCNC 13107), we have taken four spectra (600s each) with the 10.4m GTC (+ OSIRIS) at the Spanish Observatorio del Roque de los Muchachos (La Palma). The spectra, covering the range 4000-10000 A were taken starting 1.8 hr post burst, and reveal several absorption features, including CIV 1548-1550, Fe II 2344, Fe II 2383, Mg II 2796-2804 at a common redshift of 1.798. We therefore suggest this to be the redshift of GRB 120326A."
