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 58424 s.
As observed by Ulysses, it had a duration of approximately 3
seconds, a 25-100 keV fluence of approximately 2.4E-06 erg/cm2, and a
peak flux of approximately 3.4E-07 erg/cm2 s over 0.50 seconds.
We have triangulated it to a preliminary annulus centered at RA,
Decl(2000)= 171.796, +41.728 degrees, whose radius is 50.029 +/- 0.127
degrees (3 sigma ).
This annulus may be constrained and/or improved, but it is not known at
this point whether this event was observed by Mars Odyssey, and thus
whether a small error box can be derived for it.
