Sbarufatti (PSU), D.N. Burrows (PSU) and\nM. Williams (PSU), report on behalf of the Swift-XRT team:\n\nSwift XRT has continued to observe GRB 221009A  from 159s to 100 ks\nafter the BAT trigger. The WT-mode spectrum for the afterglow was\ngiven in GCN 32651.\n\nThe lightcurve can be best modelled as a four-component power law decay with:\nAlpha_1 : 2.6 (+0.4, -0.7)\nTbreak_1: 177.4 (+2.0, -9.6)\nAlpha_2 : 0.144 (+0.022, -0.026)\nTbreak_2: 610 (+84, -78)\nAlpha_3 : 0.31 (+0.04, -0.03)\nTbreak_3: (4.06 [+0.23, -0.19]) �� 10^3\nAlpha_4 : 1.357 (+/-0.010)\n\nWith T0 the BAT trigger time.\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/01126853.\n\nThis circular is an official product of the Swift-XRT team.",
