Leicester), C. Pagani (U.\nLeicester) and P.A. Evans (U. Leicester) report on behalf of the\nSwift-XRT team:\n\nSwift-XRT has conducted further observations of the field of the\nSwift/BAT-detected burst GRB 150323B (Cummings et al. GCN Circ. 17619).\nThe observations now extend from T0+40.4 ks to T0+483.5 ks. \n\nOf the sources reported by D'Avanzo et al. (GCN Circ. 17634), \"Source\n1\" is fading with 3-sigma significance, and is therefore likely the GRB\nafterglow.  The position of this source is RA, Dec=260.4534, +38.3179\nwhich is equivalent to:\n\nRA (J2000): 17:21:48.83\nDec(J2000): +38:19:04.6\n\nwith an uncertainty of 4.3 arcsec (radius, 90% confidence).  This\nposition is 18 arcsec from the Swift/BAT position.  The source is\nfading with alpha >0.3.\n\nThe results of the XRT-team automatic analysis of the likely afterglow\nare at http://www.swift.ac.uk/ToO_GRBs/00020485/index_1.php.\nThe results of the full analysis of the XRT observations are available\nat http://www.swift.ac.uk/ToO_GRBs/00020485.\n\nThis circular is an official product of the Swift-XRT team.",
