of the HETE WXM Team report:


HETE Trigger H2734, detected at 04:14:29 UT on 9 June 2003, was
due to a short burst from SGR1806-20.  This burst had a duration 
of ~100 ms and a 30-100 keV fluence of 6 x 10^-8 erg/cm2.  The 
position was not circulated automatically because the spacecraft
aspect had not yet been determined.

This detection may indicate the onset of a new period of activity 
for this SGR.
