Leicester) and P.A. Evans\n(U. Leicester) reports on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the IPN-detected\nburst GRB 230906A (Kozyrev et al., GCN Circ 34637), collecting 4.7 ks\nof Photon Counting (PC) mode data between T0+93.0 ks and T0+106.0 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):  79.7533  =  05:19:0.79\n  Dec (J2000.0): -47.8930  =  -47:53:34.9\n  Error: 6.4 arcsec (radius, 90% conf.)\n  Count-rate: (1.73 [+0.88, -0.67])e-3 ct s^-1\t \n  Distance: 23 arcsec from IPN position.\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/00021621.\n\nThis circular is an official product of the Swift-XRT team.\n\n",
