Page (U.\nLeicester)  reports on behalf of the Swift-XRT team:\n\nWe have analysed 5.7 ks of Photon Counting (PC) mode XRT data for the\nSwift/BAT-detected burst GRB 170112A, collected between T0+73 s and\nT0+13.3 ks. \n\nNo X-ray sources have been detected consistent with being within 296\narcsec of the Swift/BAT position. The 3-sigma upper limit in the field\nranges from ~0.002 to ~0.003 ct s^-1, corresponding to a 0.3-10 keV\nobserved flux of 7.8e-14 to 1.1e-13 erg cm^-2 s^-1 (assuming a typical\nGRB spectrum).\n\nSix uncatalogued sources were detected too far from the GRB position to\nbe likely afterglow candidates.\n\nThe results of the XRT-team automatic analysis of the XRT observations,\nincluding a position-specific upper limit calculator, are available at\nhttp://www.swift.ac.uk/ToO_GRBs/00732188.\n\nThis circular is an official product of the Swift-XRT team.",
