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

This burst was observed by Ulysses, Mars Odyssey (GRS), and
INTEGRAL (SPI-ACS) at 28275 s.

As observed by Ulysses, it had a duration of approximately  10
seconds, a 25-100 keV fluence of approximately  6.2E-06 erg/cm2, and a
peak flux of approximately  7.6E-07 erg/cm2 s over 0.25 seconds.

We have triangulated it to two alternate, preliminary, 3 sigma error
boxes each with approximate area 24000 square arcminutes whose
coordinates are:

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