Leicester) and P.A. Evans (U.\nLeicester) report on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the\nSwift/BAT-detected burst GRB 151122A (David Palmer et al. GCN Circ.\n18637), collecting 3.0 ks of Photon Counting (PC) mode data between\nT0+102.9 ks and T0+114.0 ks.\n\nTwo uncatalogued X-ray sources have been detected inside or close to\nthe Swift/BAT error region, however none of them is above the RASS\nlimit or shows definitive signs of fading. Therefore, at the present\ntime we cannot identify which, if any, is the afterglow. Details of\nthese sources are given below:\n\nSource 1:\n   RA (J2000.0):  299.6973  =  19:58:47.35\n   Dec (J2000.0): -19.9063  =  -19:54:22.8\n   Error: 4.7 arcsec (radius, 90% conf.)\n   Count-rate: 0.0100 �� 0.0023 ct s^-1\n   Flux: (4.24 �� 0.95)e-13 erg cm^-2 s^-1 (observed, 0.3-10 keV)\nThis source is 5.8\" away from PMN J1958-1954, classified in SIMBAD as a \nradio source.\n\nSource 2:\n   RA (J2000.0):  299.6668  =  19:58:40.03\n   Dec (J2000.0): -19.9360  =  -19:56:09.5\n   Error: 4.9 arcsec (radius, 90% conf.)\n   Count-rate: (3.9 �� 1.6)e-3 ct s^-1\n   Flux: (1.57 �� 0.64)e-13 erg cm^-2 s^-1 (observed, 0.3-10 keV)\nThis source is 2.1\" from HD 189004, a high proper-motion, K star.\n\nAnother uncatalogued was also detected, however this was too far from\nthe GRB position to be the afterglow.\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/00020560.\n\nThis circular is an official product of the Swift-XRT team.",
