Iceland) and Valerio D'Elia (ASDC and INAF/OAR) report on\nbehalf of a larger collaboration:\n\nWe observed the afterglow of GRB 090926B (Grupe et al, GCN 9935;\nMorii et al., GCN 9943). Using FORS2 on the Very Large Telescope,\nwe have obtained 3*30 min spectra (300V grating) of the optical\nafterglow candidate (Malesani et al., GCN 9944). Observations\ncommenced roughly 8 hours after the burst.\n\nThe combined spectrum shows an emission line, presumably\ncorresponding to [O II] 3727 at z = 1.24. At his redshift we\nfind several other absorption features, including Mg II, Fe II\nand Al III. Hence, we interpret the spectrum as a combination\nof the GRB afterglow and the host galaxy.\n\nWe acknowledge excellent support from the ESO observing staff,\nin particular Yuri Beletsky and Stephane Brillant.",
