Evans (U. Leicester)\nreport on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the INTEGRAL-detected\nburst GRB 200914A (Mereghetti et al. GCN Circ. 28419), collecting 3.2\nks of Photon Counting (PC) mode data between T0+8.9 ks and T0+49.2 ks. \n\n\nOne uncatalogued X-ray source has been detected consistent with being\nwithin 148 arcsec of the INTEGRAL 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 1:\n  RA (J2000.0):  254.5202  =  16:58:4.84\n  Dec (J2000.0): -36.2782  =  -36:16:41.6\n  Error: 6.5 arcsec (radius, 90% conf.)\n  Count-rate: (2.42 [+1.23, -0.93])e-3 ct s^-1\t \n  Distance: 53 arcsec from INTEGRAL position.\n  Flux: (10.0 [+5.0, -3.8])e-14 erg cm^-2 s^-1 (observed, 0.3-10 keV)\n\nWithin the 90% error circle of Source 1 we note the presence of a\nrelatively bright IR source reported in the 2MASS and AllWISE\ncatalogues (2MASS 16580467-3616436 / AllWISE J165804.63-361643.5).\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/00021033.\n\nThis circular is an official product of the Swift-XRT team.",
