of Konus-Wind and Helicon/Coronas-F teams,
A. von Kienlin, G. Lichti, and A. Rau, on behalf of the
INTEGRAL SPI-ACS GRB team, and
T. Cline, on behalf of the Ulysses and Konus GRB teams, report:
Ulysses, Konus-Wind, INTEGRAL (SPI-ACS), and Helicon/Coronas-F
observed this GRB at 20324 seconds. As observed by Ulysses, it had a
duration of approximately 10 seconds, a 25-100 keV fluence of
approximately 4.6E-06 erg/cm2, and a peak flux of approximately
1.3E-06 erg/cm2 s over 0.25 seconds.
We have triangulated it to a preliminary annulus centered at RA,
Decl(2000)= 338.090, -41.009 degrees, whose radius is 77.935 +/- 0.021
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.
