Kuin (UCL-MSSL), K. L. Page (U Leicester),\nD. M. Palmer (LANL) and B. Sbarufatti (INAF-OAB/PSU) report on behalf\nof the Swift Team:\n\nAt 09:37:23 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 170626A (trigger=758766).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 165.414, +56.469 which is \n   RA(J2000) = 11h 01m 39s\n   Dec(J2000) = +56d 28' 09\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a multi-peaked\nstructure with a duration of about 15 sec.  The peak count rate\nwas ~35000 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nThe XRT began observing the field at 09:38:21.6 UT, 58.5 seconds after\nthe BAT trigger. XRT found a bright, uncatalogued X-ray source located\nat RA, Dec 165.3927, 56.4759 which is equivalent to:\n   RA(J2000)  = +11h 01m 34.25s\n   Dec(J2000) = +56d 28' 33.2\"\nwith an uncertainty of 5.3 arcseconds (radius, 90% containment). This\nlocation is 49 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\nThe initial flux in the 2.5 s image was 1.52e-09 erg cm^-2 s^-1 (0.2-10\nkeV). \n\nThe XRT position is 5.4 arcmin away from a magnitude 2 star (Merak),\ntherefore there are no UVOT data for this burst. \n\nBurst Advocate for this burst is F. E. Marshall (marshall AT milkyway.gsfc.nasa.gov). \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.)",
