Wood-Vasey (Harvard/CfA), and J. X. Prochaska  \n(UC Santa Cruz) report on behalf of a larger collaboration:\n\n\"The final X-ray afterglow position (Perri et al. 2006; GCN 5885) of  \nthe short-hard GRB 061201 (Marshall et al. 2006; GCN 5881) lies 8.5  \narcmin from the center of the rich Abell cluster 995 (Bloom 2006; GCN  \n5880). On 13 December 2006 UT, we obtained several spectra of bright  \napparent cluster members with the LDSS-3 instrument mounted on the  \nMagellan Clay 6.5m Telescope in Chile. We find the following  \nredshifts based upon a preliminary inspection of the spectra:\n\n    \t\t\t\t     RA (J2000)          DEC(J2000)\n\t\t\t\t===========================\n      object A: z=0.239      22:08:32.1              -74:34:47\n      object B: z=0.235      22:09:37.1              -74:26:39\n      object D: z=0.238      22:09:05.3              -74:29:29\n\nBased on this, we claim a redshift of z=~0.237 for Abell 995 and note  \nthat while the GRB is not yet definitively associated with a cluster  \nmember galaxy, this redshift (and hence the implied energetics of the  \nevent) are very similar to the putative redshifts of short-hard GRBs  \n050509b (z=0.225), 050724 (z=0.258), and 060502b (z=0.287).\"\n\nThis message may be cited.",
