report:

Ulysses, INTEGRAL (SPI-ACS), Mars Odyssey (HEND and GRS), and
Konus-Wind  observed this GRB at 85670 seconds.  As observed by
Ulysses, it had a duration of approximately 10 seconds, a 25-100 keV
fluence of approximately  1.5E-06 erg/cm2, and a peak flux of
approximately  9.7E-07 erg/cm2 s over 0.25 seconds.

We have triangulated it to two alternate, preliminary, 3 sigma error
boxes each with approximate area 1020 square arcminutes, whose
coordinates are:

    RA(2000)                              DEC(2000)

 ERROR BOX CORNER 8:  6 h 29 m  9.93 s    -19 o 44 '  31.80 " 

There is a chance that the ambiguity can be resolved by further processing.
These error boxes may be improved.
