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

D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W.
Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team,

E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, and

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

Ulysses, RHESSI, Konus-Wind, and INTEGRAL (SPI-ACS) observed this GRB
at 32605 seconds.  As observed by Ulysses, it had a duration of
approximately 105 seconds, a 25-100 keV fluence of approximately
5.2E-06 erg/cm2, and a peak flux of approximately  8.4E-07 erg/cm2 s
over 0.50 seconds.

We have triangulated it to a preliminary annulus centered  at RA,
Decl(2000)= 152.354, 36.983 degrees, whose radius is 66.151 +/-  0.034
degrees (3 sigma ).  In addition, the Konus ecliptic latitude response
limits the arrival direction to ecliptic latitudes between -48 and -32
degrees, that is, to that portion of the annulus between RA, Decl =
101.6, -9.1 degrees and 164.0, -28.2 degrees.

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