(INAF-IASFPA) and P.A. Evans (U. Leicester) report on behalf of the
Swift-XRT team:

Swift-XRT has performed follow-up observations of the MAXI-detected
burst GRB 160102A (Itoh et al. GCN Circ. 18801) in a series of
observations tiled on the sky. The total exposure time is 1.8 ks,
distributed over 7 tiles; the maximum exposure at a single sky location
was 597 s. The data were collected between T0+10.8 ks and T0+17.0 ks,
and are entirely in Photon Counting (PC) mode. 

No X-ray sources have been detected. The 3-sigma upper limit in the
field (not including the regions where the tiles overlap) ranges from
~0.03 to ~0.07 ct s^-1, corresponding to a 0.3-10 keV observed flux of
1.0e-12 to 2.8e-12 erg cm^-2 s^-1 (assuming a typical GRB spectrum).

The results of the XRT-team automatic analysis of the tiled XRT
observations, including a position-specific upper limit calculator, are
available at http://www.swift.ac.uk/xrt_products/TILED_GRB00052.
