Hurley on behalf of the HETE \nFREGATE Team;\n\nwrite:\n\nAt 15:35:15.64 UTC (56115.64 s UT) on 27 August, the HETE FREGATE and \nWXM instruments detected and localized a short burst from the soft\ngamma repeater SGR1900+14. This burst is the first event from this source\nlocalized by the WXM this year, and possibly indicates the onset of \nan active period for SGR1900+14.  The coordinates (J2000) of the burst are:\n\n  R.A. = 286.856 (19h07m25s.51)\n\n  Dec. =  +9.14 (+9o08'43\")\n\nThe 90% confidence error circle for this localization is 16 arcmin in \nradius.  SGR1900+14 lies 11 arcmin from the center of the WXM error circle.\n\nThe burst duration in the 8-40 keV band was ~50 ms. A total of 207 \ncounts were detected during that interval, corresponding to a fluence \nof ~4 x 10-8 ergs cm-2 . The peak flux was >1 x 10-6 ergs cm-2 s \n(ie >40 x Crab flux).\n\nThis message may be cited.",
