D�Elia (ASDC) reports on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the Fermi/LAT-detected burst GRB 170127C (Bissaldi et al., GCN Circ 20543, Moretti et al., GCN Circ 20544)  in a series of observations tiled on the sky. The total exposure time is 5 ks, distributed over 7 tiles; the maximum exposure at a single sky location was 1.4 ks. The data were collected between T0+61.2 and T0+77.4 ks and are entirely in Photon Counting (PC) mode. \n\nNo new source is detected in the XRT field of view, at a count rate limit in the range 0.005-0.01 cts/s.\n\nThe results of the XRT-team automatic analysis of the tiled XRT observations, including a position-specific upper limit calculator, areavailable at http://www.swift.ac.uk/xrt_products/TILED_GRB00063.\n\nThis circular is an official product of the Swift-XRT team.",
