D'Avanzo (INAF-OAB), V. D'Elia (ASDC)\nand P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team:\n\nSwift-XRT has conducted further observations of the field of the\nSwift/BAT-detected burst GRB 171010B (Palmer et al. GCN Circ. 21995).\nThe observations now extend from T0+91.1 ks to T0+614.5 ks. \n\nOf the sources reported by Sbarufatti et al. (GCN Circ. 22009), \"Source\n2\" is  believed to be the afterglow.  The position of this source is\nRA, Dec=34.1342, -54.3915 which is equivalent to:\n\nRA (J2000): 02:16:32.20\nDec(J2000): -54:23:29.2\n\nwith an uncertainty of 5.6 arcsec (radius, 90% confidence).  This\nposition is 71 arcsec from the Swift/BAT position. \n\nThe light curve can be modelled with a power-law decay with a decay\nindex of alpha=0.8 (+0.6, -0.4).\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/00020780.\nThe results of the full analysis of the XRT observations are available\nat http://www.swift.ac.uk/ToO_GRBs/00020780.\n\nThis circular is an official product of the Swift-XRT team.",
