GCN circ\n7924) at 2008 July 02 at 17:38 UT, 17.3 hours after the burst. In 4 ks\nof XRT data we do not detect any sources within the refined error circle\npresented in GCN Circ 7924, down to a 3-sigma upper limit of 2.2 x 10-3\ncounts s-1.\n\nThere are two sources within the original error circle in GCN Circ 7924.\nThe brightest lies at RA, Dec=355.6326, -5.5318 degrees, with an\nestimated uncertainty of 4.7\" (radius, 90% confidence). This is\ncoincident with a known optical source, and is not fading; this is\nthus not the GRB afterglow.\n\nThe second object lies at RA,Dec=355.5665, -5.51410, which is equivalent\nto:\n\nRA (J2000)  = 23 42 15.95\nDec (J2000) = -05 30 50.8\n\nwith an estimated uncertainty of 6.3\" (radius, 90% containment). The\nsource count rate is around 3e-3 counts per second, and we are  unable\nto determine at present whether this source is fading.\n\nIn 3.7 ks of UVOT data obtained using the White filter, no new sources are\ndetected. The 3-sigma upper limit at the position of the second XRT source\nis 22.4 mag.\n\n\nThis circular is an official product of the Swift team.",
