Combining all of the data for this event (GCN 1786, 1787, 1790, and
1792) constrains the annulus given in GCN 1792 further. The arrival
direction is that portion of the annulus (centered at RA, Decl(2000)=
1.888, -37.630 degrees, radius 14.843 +/- 0.137 degrees) between RA,
Decl = 344, -34 degrees, and 348, -49 degrees. Only small improvements
to this localization are expected at this stage.

Ulysses and Konus-Wind observed this GRB at 83938 seconds.
As observed by Ulysses, it had a duration of approximately 8 seconds,
a 25-100 keV fluence of approximately 4.2E-06 erg/cm2, and a peak flux
of approximately 8.9E-7 erg/cm2 s over 0.5 seconds.
We have triangulated it to a preliminary annulus centered at RA, Decl(2000)=
1.888, -37.630 degrees, whose radius is 14.843 +/- .137 degrees (3 sigma ).
The Konus ecliptic latitude response constrains the arrival direction
to a band between ecliptic latitudes -20 and -40 degrees, that is, to those
portions of the annulus north of RA, Decl= 349, -49 and 20, -35 degrees.
This annulus can be improved, but as the event was not observed by
Mars Odyssey, a small error box cannot be derived for it.
