Price (IfA, Hawaii)\nreport on behalf of a larger collaboration:\n\nWe have imaged the region of the 4s-duration GRB060505 (GCNs 5076; 5078;\n5114; 5115) with the GMOS instrument on the Gemini South Telescope, in g'\nand r'-bands, on 2006 May 6.4 and on 2006 May 12.3.\nInspection of single g' and r'-band images from each night reveals the\npresence of a variable source 4.\"3 from the z=0.089 galaxy 2dFGRS\nS173Z112 (7kpc in projection). The afterglow coordinates are:\n\n           22:07:03.44 -27:48:51.9   (J2000.0)\n\nrelative to the USNO-A2.0 catalog.\nThe OT is found 6\" from the nominal XRT coordinates\n(which have 4.\"7 uncertainty, 90% confidence).\n\nOn 2006 May 6.40, the g'-band magnitude of the proposed afterglow was\ng~21.5,\nand on 2006 May 12.31 it was g'~22 (Compared to USNO-A2.0).\n\nWe further inspected the publicly available 2dF spectra\nof the z=0.089 galaxy 2dFGRS S173Z112, found within the XRT error circle\nof GRB 060505 (GCN 5078).\nThe spectra shows prominent emission lines of Halpha, Hbeta, OI, OII, OIII\nand SII. In absorption we detect the G-band and the CaII H line (but not\nthe K line). The spectrum suggests this is a late type galaxy."
