D'Elia (SSDC & INAF-OAR), B.\nSbarufatti (INAF-OAB) and P.A. Evans (U. Leicester) reports on behalf\nof the Swift-XRT team:\n\nSwift-XRT has conducted further observations of the field of the\nINTEGRAL-detected burst GRB 250114B. The observations now extend from\nT0+11.4 ks to T0+153.7 ks and have a total exposure time of 9.8 ks. .\nThe source previously reported, \"Source 2\", is believed to be the\nafterglow.  The position of this source is RA, Dec=48.8582, -2.2940\nwhich is equivalent to:\n\nRA (J2000): 03:15:25.96\nDec(J2000): -02:17:38.2\n\nwith an uncertainty of 7.6 arcsec (radius, 90% confidence).  This\nposition is 81 arcsec from the INTEGRAL position and consistent with\nthe reported optical counterpart (Sasada et al. GCN 38950).  Comparison\nof individual observations show the source has faded.\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/00021756.\nThe results of the full analysis of the XRT observations are available\nat https://www.swift.ac.uk/ToO_GRBs/00021756.\n\nThis circular is an official product of the Swift-XRT team.\n\n",
