Sbarufatti (INAF-OAB/PSU) report on behalf\nof the Swift Team:\n\nAt 04:55:16 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 150314A (trigger=634795).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 126.659d, +63.833d which is \n  RA(J2000) = 08h 26m 38s\n  Dec(J2000) = +63d 50' 00\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single complex peak\nstructure with a duration of about 15 sec.  The peak count rate\nwas ~45000 counts/sec (15-350 keV), at ~1 sec after the trigger. \n\nThe XRT began observing the field at 04:56:17.9 UT, 85.1 seconds after\nthe BAT trigger. XRT found a bright, uncatalogued X-ray source located\nat RA, Dec 126.6756, 63.8321 which is equivalent to:\n   RA(J2000)  = +08h 26m 42.14s\n   Dec(J2000) = +63d 49' 55.6\"\nwith an uncertainty of 4.8 arcseconds (radius, 90% containment). This\nlocation is 26 arcseconds from the BAT onboard position, within the BAT\nerror circle. No event data are yet available to determine the column\ndensity using X-ray spectroscopy. \n\nUVOT data is not immediately available. \n\nBurst Advocate for this burst is L. M. Z. Hagen (lea.zernow.hagen AT gmail.com). \nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/too.html.)",
