Sbarrato (INAF-OAB) and P.A.\nEvans (U. Leicester) report on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the MAXI-detected\nburst GRB 220514B (Y. Kawakubo et al. GCN Circ. 32046) in a series of\nobservations tiled on the sky. The total exposure time is 1.9 ks,\ndistributed over 4 tiles; the maximum exposure at a single sky location\nwas 1.0 ks. The data were collected between T0+57.9 ks and T0+60.1 ks,\nand are entirely in Photon Counting (PC) mode. \n\nNo X-ray sources have been detected. The 3-sigma upper limit in the\nfield (not including the regions where the tiles overlap) ranges from\n~0.02 to ~0.04 ct s^-1, corresponding to a 0.3-10 keV observed flux of\n6.7e-13 to 1.4e-12 erg cm^-2 s^-1 (assuming a typical GRB spectrum).\n\nThe results of the XRT-team automatic analysis of the tiled XRT\nobservations, including a position-specific upper limit calculator, are\navailable at https://www.swift.ac.uk/xrt_products/TILED_GRB00106.\n\nThis circular is an official product of the Swift-XRT team.",
