Sbarufatti (INAF-OAB) report on behalf\nof the Neil Gehrels Swift Observatory Team:\n\nAt 21:00:35 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated a bright burst from the Soft Gamma Repeater SGR 1806-20\n(trigger=1159327).  Swift did not immediately slew to the source. \nThe BAT on-board calculated location is \nRA, Dec 272.154, -20.416 which is \n   RA(J2000) = 18h 08m 37s\n   Dec(J2000) = -20d 24' 56\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve shows a single spike\nstructure with a duration of about 0.6 sec.  The peak count rate\nwas ~170,000 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nXRT follow-up observations are planned.",
