Ofek (Caltech) report:\n\n\"We note the presence of two 2MASS-cataloged galaxies within the BAT\nlocalization region for the short-hard burst GRB 070923 (Stroh et al.,\nGCN 6818).  The galaxy coordinates, distances (D) from the center of\nthe BAT error circle in arcmin, and total broadband magnitudes (J, H,\nKs) as given by the NASA/IPAC Extragalactic Database* are:\n\n            RA (J2000)   Dec (J2000)   D      J      H     Ks\n   =================================================================\n   2MASS-A  12:18:29.35  -38:16:44.1  0.7   15.01  14.77  13.73\n   2MASS-B  12:18:21.87  -38:18:24.0  2.8   15.35  14.44  13.88\n   =================================================================\n\nAlthough neither galaxy has a measured redshift, the somewhat more\ndistant galaxy 2MASX J12180474-3818108 (D=5.4 arcmin) and 2MASX\nJ12175556-3818208 (D=7.2 arcmin) both have z~0.076 according to the\n6dF redshift survey (Jones et al. 2004).\"\n\n\n*This research has made use of the NASA/IPAC Extragalactic Database\n(NED) which is operated by the Jet Propulsion Laboratory, California\nInstitute of Technology, under contract with the National Aeronautics\nand Space Administration.",
