GCN Circular 7616
A. Cucchiara and D. B. Fox (Penn State) with S. B. Cenko (Caltech), report on behalf of a larger collaboration: "Starting on 2008 April 13.27 UT we observed GRB 080413A (GCN 7593 and 7594) with the GMOS spectrograph on the Gemini South telescope. We obtained 2x1200-sec spectra in the wavelength range 3900-8000A. The resolution of our spectrum is 5.2 Ang/pixel (R ~1200 at 6000A). We clearly observe several metal absorption features corresponding to the SiIV (1393,1402 A), CIV (1548, 1550A), SiII (1526A), and AlII (1670A) transitions. A Lyman break is also present at the blue edge of our spectra (~ 4170A). These identifications are consistent with a host galaxy redshift of z = 2.43, confirming the result reported from VLT observations by Thoene et al.(GCN 7602)."
