K. Hurley, on behalf of the Ulysses GRB team,
T. Cline, on behalf of the Ulysses and Konus-Wind GRB teams, and
E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, report:
Ulysses and Konus-Wind observed this GRB at 47292 seconds. As
observed by Ulysses, it had a duration of approximately 3 seconds, a
25-100 keV fluence of approximately 6.1E-06 erg/cm2, and a peak flux of
approximately 1.4E-06 erg/cm2 s over 0.25 seconds.
We have triangulated it to a preliminary annulus centered at
RA, Decl (2000)=171.715, 38.791 degrees, whose radius is
88.681 +/-0.030 degrees (3 sigma).
This event was not observed by Mars Odyssey, so we will not
be able to obtain a small error box for it. We are waiting
for more Konus data, however, which may allow us to determine
the ecliptic latitude and exclude part of the annulus.
