and A. Zehnder, on behalf of the RHESSI GRB team, report:
Ulysses and RHESSI also observed this burst (GCN 2235), As observed by
Ulysses, it had a duration of approximately 12 seconds, a 25-100 keV
fluence of approximately 2.9E-05 erg/cm2, and a peak flux of
approximately 4.3E-06 erg/cm2 s over 0.50 seconds.
We have triangulated it to a preliminary annulus centered at RA,
Decl(2000)= 331.653, -35.097 degrees, whose radius is 71.871 +/- 0.018
degrees (3 sigma). This annulus intersects the HETE WXM error box and
reduces its area to ~35 square arcminutes. The coordinates of the
IPN/WXM error box are:
ERROR BOX CENTER : 241.152 -33.473
ERROR BOX CORNER 1: 241.020 -33.623
ERROR BOX CORNER 2: 241.073 -33.621
ERROR BOX CORNER 3: 241.231 -33.325
ERROR BOX CORNER 4: 241.284 -33.323
This error box may be improved.
