A. von Kienlin, G. Lichti, and A. Rau, on behalf of the
INTEGRAL SPI-ACS GRB team, report:

Ulysses, Mars Odyssey (HEND and GRS), HETE-FREGATE (H2662), INTEGRAL (SPI-ACS),
and Konus-Wind observed this GRB at 08248 seconds.  As observed by
Ulysses, it had a duration of approximately 5 seconds, a 25-100 keV
fluence of approximately  4.3E-06 erg/cm2, and a peak flux of
approximately  1.0E-06 erg/cm2 s over 0.25 seconds.

We have triangulated it to a preliminary, 3 sigma error box whose
approximate area is 36 sq. arcmin. and whose coordinates are:

    RA(2000)                              DEC(2000)
 ERROR BOX CENTER:  16 h 33 m 06.33 s    -24 o 09 '  08.86 " 
 ERROR BOX CORNER 1: 16 h 33 m 06.62 s    -24 o 07 '  34.35 " 
 ERROR BOX CORNER 2: 16 h 33 m 58.27 s    -23 o 52 '  17.70 " 
 ERROR BOX CORNER 3: 16 h 32 m 14.93 s    -24 o 25 '  49.05 " 
 ERROR BOX CORNER 4: 16 h 33 m 06.05 s    -24 o 10 '  43.30 " 

This error box may be improved.
