Tagliaferri\n(INAF-OAB) report on behalf of the Swift-XRT team:\n\nThe XRT began observing the field of GRB 150722A at 10:51:48.0 UT,\n3234.9 seconds after the BAT trigger. Using promptly downlinked data we\nfind a fading, uncatalogued X-ray source located at RA, Dec 218.27775,\n-35.19644 which is equivalent to:\n   RA(J2000)  = 14h 33m 06.66s\n   Dec(J2000) = -35d 11' 47.2\"\nwith an uncertainty of 3.6 arcseconds (radius, 90% containment). This\nlocation is 17 arcseconds from the BAT onboard position, within the BAT\nerror circle. This position may be improved as more data are received;\nthe latest position is available at http://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 5.92\nx 10^20 cm^-2 (Willingale et al. 2013).",
