Fox (PSU) report:\n\n\"We obtained spectroscopic observations of the SDSS galaxy located inside\nthe XRT error circle of GRB 090417B (GCNs 9153, 9155, 9140) with GMOS on\nthe Gemini-North telescope.  In a combined 1800 sec spectrum we detect\nemission lines corresponding to [OII]3727, [OIII]5006, and H-alpha at a\nredshift of z=0.345.  At this redshift the observed fluence of the burst\n(2.3e-6 erg/cm^2; GCN 9139) translates to an isotropic-equivalent energy\nof 9e50 erg.\"",
