  "body": "C. Salvaggio (INAF-OAB), K. L. Page (U. Leicester) and P.A. Evans (U.\nLeicester) reports on behalf of the Swift-XRT team:\n\n\nSwift-XRT has performed further follow-up observations of the IPN-detected\nburst GRB 240715A (Kozyrev et al., GCN Circ. 36872). The data were\ncollected between T0+36.0 ks ks and T0+1270 ks,  for a total exposure time\nof 17.7 ks.\n\n\nThe uncatalogued X-ray source reported by D'Elia et al. (\"Source 3\"; GCN\nCirc. 36890), with a count-rate of 4.0 [+1.4, -1.2]e-3 ct s^-1, is no more\ndetected: we derive an upper limit of 1.4e-3 ct s^-1. Source 3 shows\nsignificant signs of fading, and is therefore likely the GRB afterglow.\n\n\nThe X-ray afterglow light curve can be modelled with a power-law with no\nbreaks and decay index alpha > 0.63.\n\n\n\nThe results of the XRT-team automatic analysis are available at\nhttps://www.swift.ac.uk/xrt_products/00021699.\n\n\nThis circular is an official product of the Swift-XRT team.\n",
