Sbarufatti (INAF-OAB/PSU) report on\nbehalf of the Swift Team:\n\nAt 23:08:33 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated an outburst from SGR1806-20 (trigger=519868).  Swift did not slew because\nof the Moon observering constraint.  The BAT on-board calculated location is \nRA, Dec 272.153, -20.410 which is \n   RA(J2000)  =  18h 08m 37s\n   Dec(J2000) = -20d 24' 35\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve shows a single spike\nwith a duration of about 0.2 sec.  The peak count rate\nwas ~13,000 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nDue to an observing constraint Swift will be unable to observe this\nfield with the XRT and UVOT instruments until 12 April at 14:00 UT.",
