Evans (U.\nLeicester) report on behalf of the Swift-XRT team:\n\nThe XRT began observing the field of GRB 140311B at 22:11:04.3 UT,\n3394.7 seconds after the BAT trigger. Using promptly downlinked data we\nfind an uncatalogued X-ray source located at RA, Dec 252.32458,\n52.72393 which is equivalent to:\n   RA(J2000)  = 16h 49m 17.90s\n   Dec(J2000) = +52d 43' 26.1\"\nwith an uncertainty of 3.6 arcseconds (radius, 90% containment). This\nlocation is 110 arcseconds from the BAT onboard position, within the\nBAT error circle. This position may be improved as more data are\nreceived; the latest position is available at\nhttp://www.swift.ac.uk/sper. \n\nA power-law fit to a spectrum formed from promptly downlinked event\ndata gives a column density consistent with the Galactic value of 3.03\nx 10^20 cm^-2 (Kalberla et al. 2005).",
