The data are entirely in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Evans et al. (GCN Circ. 29113). The source is fading with alpha >0.4. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/01014037. This circular is an official product of the Swift-XRT team.
