GCN Circular 6083
A. Cucchiara (PSU), D. B. Fox (PSU), S. B. Cenko (Caltech) and P. A. Price (Hawaii) report on behalf of a larger collaboration: "We observed the optical afterglow (Guidorzi et al., GCN 6077, Fox et al., GCN 6078) of GRB 070208 (Sato et al., GCN 6074) with the Gemini-North telescope + Gemini Multi-Object Spectrograph in four 1800-s integrations with mean epoch 11:37 UT on 8 Feb 2007 (approximately 2.5 hours after the burst). Our spectral coverage is 4000-8300 A. The bright nearby galaxy seen in archival images (e.g., Mirabal & Halpern, GCN 6075) does not fall within our slit. At the afterglow position we observe a strong [OII] (3727 A) emission line at redshift z=1.165 superposed on the afterglow continuum, along with multiple metal absorption features consistent with this redshift, including: the MgII (2796.4 A, 2803.5 A) doublet, FeII (2600.5 A), and MnII (2576.9 A). We conclude that the redshift of GRB 070208 and its underlying host galaxy is z=1.165."
