behalf of the HETE GRB team, report:

Ulysses, Mars Odyssey-HEND, RHESSI, Konus-Wind, INTEGRAL (SPI-ACS), and
HETE (FREGATE) observed this GRB at 23905 seconds.  As observed by
Ulysses, it had a duration of approximately 30 seconds, a 25-100 keV
fluence of approximately  1.7E-05 erg/cm2, and a peak flux of
approximately  1.1E-06 erg/cm2 s over 0.50 seconds.

We have triangulated it to a preliminary, 3 sigma error box whose
approximate area is 630 sq. arcmin. and whose coordinates are:

    RA(2000)                              DEC(2000)
 ERROR BOX CENTER:   16 h 54 m 49.80 s   -21 o  6 '  43.99 "
 ERROR BOX CORNER 1:  16 h 54 m 40.02 s  -21 o  9 '  31.55 " 
 ERROR BOX CORNER 2:  16 h 59 m  3.59 s  -18 o 43 '   7.78 " 
 ERROR BOX CORNER 3:  16 h 50 m 23.70 s  -23 o 36 '  56.65 " 
 ERROR BOX CORNER 4:  16 h 54 m 59.57 s  -21 o  3 '  56.62 " 

This error box may be improved, but as Ulysses, the Earth, and
Mars are practically aligned, a small error box cannot be derived
for this event.
