Ulysses and Konus-Wind also observed this GRB (HETE 2449, GCN 1686).
We have triangulated it to a preliminary annulus centered  at RA, Decl(2000)=
1.104, -35.210 degrees, whose radius is 78.410 +/-  0.078 degrees (3 sigma ).
This intersects the WXM error box given in GCN 1686 at four points, and
reduces its area by about 30%.  The intersection points are:

  RA(2000)               DECL(2000)
1 h 32 m 44.80 s      40 o 26 ' 18.72 "
1 h 33 m 46.40 s      40 o 32 ' 15.63 "
1 h 35 m 00.19 s      40 o 27 ' 32.32 "
1 h 33 m 28.89 s      40 o 23 ' 31.68 "

This annulus can be improved, but as Mars Odyssey was recovering
from safe mode, a small error box cannot be derived for it.
