Burrows (PSU) and P.A.\nEvans (U. Leicester) reports on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the\nSVOM/ECLAIRs-detected burst GRB 240914A, collecting 1.9 ks of Photon\nCounting (PC) mode data between T0+36.3 ks and T0+42.4 ks. \n\nNo uncatalogued X-ray sources have been detected. The 3-sigma upper\nlimit in the field ranges from ~0.005 to ~0.006 ct s^-1, corresponding\nto a 0.3-10 keV observed flux of 1.9e-13 to 2.3e-13 erg cm^-2 s^-1\n(assuming a typical GRB spectrum).\n\nThree previously-catalogued X-ray sources have been detected, however\ntheir status as catalogued objects makes them unlikely to be the\nafterglow.\n\nThe results of the XRT-team automatic analysis of the XRT observations,\nincluding a position-specific upper limit calculator, are available at\nhttps://www.swift.ac.uk/ToO_GRBs/00021716.\n\nThis circular is an official product of the Swift-XRT team.\n\n",
