W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr, on
behalf of the GRS-Odyssey GRB team, report:

Ulysses, INTEGRAL (SPI-ACS), and Mars Odyssey (HEND) observed this
burst at 80086 s.  As observed by Ulysses, it had a duration of
approximately 6 seconds, a 25-100 keV fluence of approximately
3.0E-06 erg/cm2, and a peak flux of approximately  1.1E-06 erg/cm2 s
over 0.25 seconds.

We have triangulated it to two alternate, preliminary, 3 sigma error
boxes each with approximate area 10000 square arcminutes whose
coordinates are:

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