Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team, report:
Ulysses, Konus-Wind, Mars Odyssey-HEND and GRS, and RHESSI observed
this GRB at 51061 seconds. As observed by Ulysses, it had a duration
of approximately 22 seconds, a 25-100 keV fluence of approximately
2.5E-05 erg/cm2, and a peak flux of approximately 1.8E-06 erg/cm2 s
over 0.50 seconds.
We have triangulated it to a preliminary, 3 sigma error box with
approximate area 1600 square arcminutes whose coordinates are:
ERROR BOX CENTER: 4 h 26 m 54.86 s -5 o 55 ' 49.00 "
ERROR BOX CORNER 4: 4 h 26 m 57.58 s -5 o 53 ' 3.70 "
ERROR BOX CORNER 5: 4 h 23 m 0.21 s -2 o 24 ' 18.37 "
ERROR BOX CORNER 6: 4 h 31 m 2.25 s -9 o 52 ' 11.05 "
ERROR BOX CORNER 7: 4 h 26 m 52.15 s -5 o 58 ' 34.45 "
Some improvement in this error box is expected, but the
data quality for some of the spacecraft is poor due to solar
activity.
