E. Berger (Carnegie) reports:
"We obtained a 2100 sec spectrum of the putative host galaxy of the short
GRB 061217 (GCN #5949). We clearly detect the [OII]3727 and [OIII]5007
emission lines at a redshift of z=0.827. The relative faintness of the
host and the higher redshift compared to early short GRBs provides
additional support to the conclusion that a substantial fraction of short
GRBs arise at z~1 (Berger et al. astro-ph/0611128). At z=0.827 the
isotropic-equivalent energy release of the burst is about 8e49 erg."
