  "body": "P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:\n\nWe have analysed 2.7 ks of XRT data for GRB 241229B, from 23.5 ks to\n34.3 ks after the  BAT trigger. The data are entirely in Photon\nCounting (PC) mode. The refined XRT position is RA, Dec = 274.1761,\n+74.6833 which is equivalent to:\n\nRA (J2000): 18 16 42.26\nDec(J2000): +74 40 60.0\n\nwith an uncertainty of 6.8 arcsec (radius, 90% confidence). The source\nhas a mean count rate of 1.4e-02 ct/sec; we cannot determine at the\npresent time whether it is fading.\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/01277428.\n\nThis circular is an official product of the Swift-XRT team.\n\n",
