Toy (UMD) \nreport on behalf of a larger collaboration:\n\nOn September 4.20 UT we observe the candidate afterglow of the short GRB \n140903A (Cummings et al. GCN 16763, Kennea et al. GCN 16764, Capone et al. \nGCN 16769) with the Gemini-North telescope equipped with the GMOS camera. \nA set of 2x600s exposures were obtained in spectroscopic mode: our spectra \ncovered the wavelength range 4000-8100 Angstroms at a resolution of R~1200. \n\nWe clearly identify a strong absorption doublet feature at the observed wavelength \n7954, 7965 Angstrom and a weak emission line at 6570 Angstrom.\nWe tentatively interpret these features as NaID in absorption and H-beta line \nin emission at the common redshift of z=0.351.\nNo other clear features are visible neither in emission nor in absorption, \ntherefore we suggest this to be the redshift of the host galaxy of GRB 140903A.\n\n\nWe thank the Gemini staff, in particular Jess Ball, for their prompt\nassistance with these observations.",
