Dichiara (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 241108A, collecting 2.9 ks of Photon\nCounting (PC) mode data between T0+43.8 ks and T0+50.6 ks. \n\nOne uncatalogued X-ray source has been detected, it is below the RASS\nlimit and shows no definitive signs of fading. Therefore, at the\npresent time we cannot confirm this as the afterglow. Details of this\nsource are given below:\n\nSource 1:\n  RA (J2000.0):  123.6378  =  08:14:33.07\n  Dec (J2000.0): -7.0861  =  -07:05:09.9\n  Error: 4.7 arcsec (radius, 90% conf.)\n  Count-rate: (5.0 [+2.0, -1.6])e-3 ct s^-1   \n  Distance: 494 arcsec from SVOM/ECLAIRs position.\n  Flux: (2.99 [+1.17, -0.93])e-13 erg cm^-2 s^-1 (observed, 0.3-10 keV)\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/00021729.\n\nThis circular is an official product of the Swift-XRT team.\n\n",
