Gehrels (NASA/GSFC) report\non behalf of the Swift-XRT team:\n\nSwift began observing the INTEGRAL-detected short GRB 071017 \n(Mereghetti et al. GCN Circ 6927) at 08:58:45 UT on 2007 October 19, 2.3\ndays after the trigger. We currently have 2 ks of XRT data, in which we\ndetect a source inside the INTEGRAL error circle at RA, Dec=274.7148,\n-15.9889 degrees, which is equivalent to:\n\nRA (J2000)  = 18:18:51.56\nDec (J2000) = -15:59:19.9\n\nwith an estimated uncertainty of 5.5 arcsec (radius, 90% confidence).\nThis is consistent with the XMM source 2XMM J171751.2-155920, and lies\nwithin the error circle reported for the transient AX J1818.8-1559\n(Sugizaki et al. 2001) thus it is not a GRB afterglow. \n\nNo other X-ray sources are detected inside the INTEGRAL error circle,\nwith a 3-sigma upper limit of 0.005 counts per second. There are two\nfurther X-ray sources in the XRT field of view, the first is at RA,\nDec=274.8069, -16.0237 with an estimated uncertainty of 6.5 arcsec\n(radius, 90% confidence), this is 5.3 arcmin away from the INTEGRAL\nposition. The second source is at RA, Dec=274.8436,-16.0552 with an\nestimated uncertainty of 7.9 arcsec (radius, 90% confidence), and is 7.9\narcmin away from the INTEGRAL position.\n\nThis circular is an official product of the Swift-XRT team.",
