K. Hurley, and T. Cline, on behalf of the Ulysses and Mars
Odyssey GRB teams,
A. von Kienlin, G. Lichti, and A. Rau, on behalf of the
INTEGRAL SPI-ACS GRB team,
I. Mitrofanov, D. Anfimov, A. Kozyrev, M. Litvak and A. Sanin, on
behalf of the HEND-Odyssey GRB team, and
W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr, on
behalf of the GRS-Odyssey GRB team, report:
This burst was observed by Ulysses, Mars Odyssey (GRS), and
INTEGRAL (SPI-ACS) at 28275 s.
As observed by Ulysses, it had a duration of approximately 10
seconds, a 25-100 keV fluence of approximately 6.2E-06 erg/cm2, and a
peak flux of approximately 7.6E-07 erg/cm2 s over 0.25 seconds.
We have triangulated it to two alternate, preliminary, 3 sigma error
boxes each with approximate area 24000 square arcminutes whose
coordinates are:
RA(2000) DEC(2000)
ERROR BOX CENTER: 17 h 42 m 27.23 s -6 o 54 ' 0.77 "
ERROR BOX CORNER 1: 17 h 43 m 21.88 s -6 o 26 ' 4.00 "
ERROR BOX CORNER 2: 17 h 28 m 12.29 s -11 o 34 ' 8.17 "
ERROR BOX CORNER 3: 18 h 11 m 36.51 s 1 o 39 ' 13.89 "
ERROR BOX CORNER 4: 17 h 41 m 35.44 s -7 o 21 ' 12.46 "
OR
ERROR BOX CENTER: 19 h 5 m 34.33 s 13 o 47 ' 0.40 "
ERROR BOX CORNER 4: 19 h 3 m 38.29 s 13 o 33 ' 56.68 "
ERROR BOX CORNER 5: 19 h 25 m 27.01 s 17 o 7 ' 58.89 "
ERROR BOX CORNER 6: 18 h 30 m 47.64 s 6 o 30 ' 24.53 "
ERROR BOX CORNER 7: 19 h 7 m 27.44 s 13 o 59 ' 17.61 "
There is a chance that the ambiguity can be resolved by further processing.
These error boxes may be improved.
