K. Hurley and T. Cline, on behalf of the Ulysses GRB team, and

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

Ulysses and INTEGRAL (SPI-ACS) observed this burst at 42158 s.
As observed by Ulysses, it had a duration of approximately 200
seconds, a 25-100 keV fluence of approximately  3.6E-05 erg/cm2, and a
peak flux of approximately  1.9E-06 erg/cm2 s over 0.50 seconds.

We have triangulated it to a preliminary annulus centered  at RA,
Decl(2000)= 351.179, -41.826 degrees, whose radius is 55.834 +/-  0.019
degrees (3 sigma ).

This annulus can be improved and/or constrained, but as the event was
not observed by Mars Odyssey, a small error box cannot be derived for
