Ulysses, Mars Odyssey-GRS, HETE-FREGATE, INTEGRAL (SPI-ACS), and
Konus-Wind observed this GRB at 27277 seconds.  As observed by Ulysses,
it had a duration of approximately  15 seconds, a 25-100 keV fluence of
approximately  2.3E-06 erg/cm2, and a peak flux of approximately
4.7E-07 erg/cm2 s over 0.25 seconds.

We have triangulated it to a preliminary, 3 sigma error box whose
approximate area is 314. sq. arcmin. and whose coordinates are:

    RA(2000)                              DEC(2000)

This error box may be improved.
