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 02192 seconds.
As observed by Ulysses, it had a duration of approximately 170 seconds,
a 25-100 keV fluence of approximately 1.3E-05 erg/cm2, and a peak flux
of approximately 1.6E-06 erg/cm2 s over 0.25 seconds.
We have triangulated it to a preliminary annulus centered at RA,
Decl(2000)= 333.729, -38.892 degrees, whose radius is 51.349 +/- 0.018
degrees (3 sigma ).
This annulus may be constrained and/or improved, but as the event was
not observed by Mars Odyssey, a small error box cannot be derived for
it.
