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 observed this burst at 16810 s. A preliminary
analysis of the Konus data indicates that it arrived from an ecliptic
latitude between -5 and +5 degrees. More Konus data should be obtained
within 72 hours which will allow us to derive a triangulation annulus
for this event, and a GCN message will be issued. Information on the
burst intensity and duration will also be given at that time. As
Mars Odyssey did not observe this burst, it will not be possible to
derive a small error box for it.

E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, report:
Further data have been obtained for this event (GCN 1547). Ulysses and
Konus observed this burst at 16810 s. As observed by Ulysses, it had a
duration of ~6 s, a 25-100 keV fluence of ~4.2 x 10^-6 erg/cm^2, and a
peak flux over 0.25 s of ~1 x 10^-6 erg/cm^2 s. We have triangulated
it to an annulus centered at RA, Decl(2000)=170.753, +39.335, with
radius 48.044 +/- 0.015 degrees (3 sigma) A preliminary analysis of
the Konus data indicates that it arrived from an ecliptic latitude
between -5 and +5 degrees. This limits the annulus to the two sections
between RA, Decl.=123.4, +14.8 and 114.5, +26.6, and between
RA, Decl.= 183.9, -7.1 and 197.4, -2.0.
As Mars Odyssey did not observe this event, it will not be possible
to derive a small error box for it.
