Leicester) and P.A. Evans\n(U. Leicester) report on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the\nSwift/BAT-detected burst GRB 190610A (Palmer et al. GCN Circ. 24783),\ncollecting 5.0 ks of Photon Counting (PC) mode data between T0+292.3 ks\nand T0+300.5 ks. \n\nOne uncatalogued X-ray source has been detected consistent with being\nwithin 187 arcsec of the Swift/BAT position, it is below the RASS limit\nand shows no definitive signs of fading. Therefore, at the present time\nwe cannot confirm this as the afterglow. Details of this source are\ngiven below:\n\nSource 7:\n  RA (J2000.0):  46.2216  =  03:04:53.17\n  Dec (J2000.0): -7.6824  =  -07:40:56.7\n  Error: 5.3 arcsec (radius, 90% conf. [Enhanced position])\n  Count-rate: (1.76 [+0.83, -0.64])e-3 ct s^-1\t \n  Distance: 111 arcsec from Swift/BAT position.\n  Flux: (1.17 [+0.55, -0.42])e-13 erg cm^-2 s^-1 (observed, 0.3-10 keV)\n\n\nWe note that the position of this afterglow candidate is consistent\nwith the galaxy SDSS J030452.77-074055.3 (r=21.5 AB), which has unknown\nredshift. \n\nFive 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\nhttp://www.swift.ac.uk/ToO_GRBs/00020896.\n\nThis circular is an official product of the Swift-XRT team.",
