Perri (SSDC & INAF-OAR)\nand P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:\n\nWe have analysed 10.4 ks of Photon Counting (PC) mode XRT data for the\nSwift-BAT-detected burst GRB 240824A, collected between T0+-897 s and\nT0+40.9 ks. \n\nOne uncatalogued X-ray source has been detected consistent with being\nwithin 3 arcmin of the Swift-BAT position, however it is not above the\nRASS limit or shows definitive signs of fading. Therefore, at the\npresent time we cannot identify it as the afterglow. Details of the\nsource are given below:\n\nSource 4:\n  RA (J2000.0):  213.1710  =  14:12:41.05\n  Dec (J2000.0): +63.7283  =  +63:43:41.7\n  Error: 5.4 arcsec (radius, 90% conf.)\n  Count-rate: (1.26 [+0.55, -0.44])e-3 ct s^-1\t \n  Distance: 59 arcsec from Swift-BAT position.\n  Flux: (3.0 [+1.3, -1.1])e-14 erg cm^-2 s^-1 (observed, 0.3-10 keV)\n\nSeven uncatalogued sources were also detected too far from the GRB\nposition to be 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\nhttps://www.swift.ac.uk/ToO_GRBs/01250282.\n\nThis circular is an official product of the Swift-XRT team.\n\n",
