TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5275 SUBJECT: GRB 060614: Redshift DATE: 06/06/20 02:56:46 GMT FROM: Paul Price at IfA,UH P.A. Price (IfA, Hawaii), E. Berger (OCIW) and D.B. Fox (Penn. State) report on behalf of a larger collaboration: We observed the afterglow of GRB 060614 (GCN #5254) with the Gemini South telescope + GMOS. Our observations consisted of 4x1800 sec exposures with the R400 grating and 1 arcsec slit, commencing at June 19.3 UTC. In each image we identify a single emission line at 7388A superposed on a continuum emission with no apparent absorption features. If this line is due to [O II], the redshift is z = 0.98. However, there is a hint of a line at 5634A which suggests that the line is actually due to Halpha at z = 0.13. In addition to the bright emission line due to the GRB host galaxy, there is a brighter emission line at the same wavelength from the galaxy 17 arcsec North of the GRB. A spectrum from the Magellan telescope reveals the presence of the [N II] doublet flanking the Halpha line for this galaxy, with a secure redshift of z = 0.125. Based on the identical wavelength of the lines, the two galaxies are likely related, at a redshift of z = 0.125; in this case, the separation in the plane of the sky is 38 kpc. Using the fluence of 2.17 x 10^-5 erg/cm^2 (GCN #5254), a redshift of z = 0.125 corresponds to an isotropic energy release of Eiso = 8.4 x 10^50 erg. We thank the Gemini South observing team for obtaining these observations.
