Leicester) report\non behalf of the Swift-XRT team:\n\n\nWe have analysed 5 ks of XRT data for the Fermi/GBM-detected burst:\nGRB 140606B,  from 184.4 ks to 192.6 ks after the  Fermi/GBM trigger.\nThe data are entirely in Photon Counting (PC) mode.\nUsing 4979 s of XRT Photon Counting mode data and 4 UVOT\nimages, we find an astrometrically corrected X-ray position (using the\nXRT-UVOT alignment and matching UVOT field sources to the USNO-B1\ncatalogue): RA, Dec =\n328.12501, 32.01458 which is equivalent to:\n\nRA (J2000):  21 52 30.00\nDec (J2000): +32 00 52.5\n\nwith an uncertainty of 2.3 arcsec (radius, 90% confidence).\nThis position is a 5.2 arcsec from source iPTF 14bfu from\nGCN Circular 16360.\n\nThis position may be improved as more data are received.  The latest\nposition can be viewed at http://www.swift.ac.uk/xrt_positions. Position\nenhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans\net al. (2009, MNRAS, 397, 1177).\n\nWe cannot determine at the present time whether the source is fading.\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/00020384.\n\nThis circular is an official product of the Swift-XRT team.",
