K. Hurley and T. Cline, on behalf of the Ulysses, Konus, and Mars Odyssey GRB teams,
I. Mitrofanov, D. Anfimov, A. Kozyrev, M. Litvak and A. Sanin,
on behalf of the HEND/Odyssey GRB team,
W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr,
on behalf of the GRS/Odyssey 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, Mars Odyssey (HEND+GRS), INTEGRAL (SPI-ACS) and Konus-Wind
observed this GRB at 51310 seconds. As observed by Ulysses, it had a
duration of approximately 2 seconds, a 25-100 keV fluence of
approximately 1.5E-06 erg/cm2, and a peak flux of approximately
1.0E-06 erg/cm2 s over 0.50 seconds.
We have triangulated it to two preliminary, 3 sigma error boxes whose
approximate areas are 220 sq. arcmin. each and whose coordinates are:
RA(2000) DEC(2000)
4 h 43 m 6.76 s -19 o 6 ' 8.18 " (CENTER)
4 h 42 m 40.72 s -18 o 56 ' 52.00 " (CORNER)
4 h 46 m 17.63 s -19 o 57 ' 38.06 " (CORNER)
4 h 39 m 37.19 s -18 o 9 ' 1.66 " (CORNER)
4 h 43 m 32.36 s -19 o 15 ' 16.64 " (CORNER)
OR
RA(2000) DEC(2000)
3 h 40 m 50.29 s -1 o 21 ' 44.35 " (CENTER)
3 h 41 m 23.69 s -1 o 29 ' 5.72 " (CORNER)
3 h 37 m 50.12 s 0 o 30 ' 18.01 " (CORNER)
3 h 44 m 9.29 s -2 o 18 ' 46.98 " (CORNER)
3 h 40 m 17.33 s -1 o 14 ' 30.76 " (CORNER)
These error boxes may be improved, and it should be possible
to remove the ambiguity.
