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.
