Salvaggio (INAF-OAB) and\nP.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the\nFermi/GBM-detected burst GRB 241002B, collecting 2.7 ks of Photon\nCounting (PC) mode data between T0+134.3 ks and T0+146.1 ks. \n\nOne uncatalogued X-ray source has been detected consistent with being\nwithin 8.2 arcsec of the candidate optical counterpart detected by\nGOTO: GOTO24gpc/AT2024xbg (Kumar et al., GCN Circ. 37694), it is below\nthe RASS limit and shows no definitive signs of fading. Therefore, at\nthe present time we cannot confirm this as the afterglow. Details of\nthis source are given below:\n\nSource 4:\n  RA (J2000.0):  328.3201  =  21:53:16.82\n  Dec (J2000.0): -58.9471  =  -58:56:49.6\n  Error: 3.2 arcsec (radius, 90% conf. [Enhanced position])\n  Count-rate: 0.0246 [+0.0037, -0.0035] ct s^-1   \n  Distance: 3 arcsec from GOTO position.\n  Flux: (1.12 [+0.17, -0.16])e-12 erg cm^-2 s^-1 (observed, 0.3-10 keV)\n\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/00021721.\n\nThis circular is an official product of the Swift-XRT team.\n\n",
