behalf of the HETE GRB team, report:

Ulysses, Mars Odyssey (HEND & GRS), INTEGRAL (SPI-ACS) and HETE
(FREGATE) observed this burst at 45930 s.  As observed by Ulysses, it
had a duration of approximately 100  seconds, a 25-100 keV fluence of
approximately  2.2E-05 erg/cm2, and a peak flux of approximately
1.1E-06 erg/cm2 s over 0.25 seconds.

We have triangulated it to a preliminary, 3 sigma error box whose
approximate area is 73 sq. arcmin. and whose coordinates are:

    RA(2000)                              DEC(2000)
 ERROR BOX CENTER:   0 h  3 m 20.47 s     32 o 43 '  36.92 " 
 ERROR BOX CORNER 1:  0 h  3 m 30.06 s     32 o 45 '  45.55 " 
 ERROR BOX CORNER 2:  0 h  4 m 26.15 s     32 o 40 '  18.06 " 
 ERROR BOX CORNER 3:  0 h  2 m 14.87 s     32 o 46 '  52.49 " 
 ERROR BOX CORNER 4:  0 h  3 m 10.89 s     32 o 41 '  28.22 " 

This error box may be improved.
