behalf of the HETE GRB team, report:

Konus-Wind and HETE-FREGATE observed this ~140 s long GRB at 21113 s.
We have triangulated it to a preliminary annulus centered at RA, Decl
(2000)= 66.273, +18.171, whose radius is 30.555 +/-  7.134 degrees (3
sigma).  In addition, the Konus ecliptic latitude response limits the
arrival directions to ecliptic latitudes between 0 and +10 degrees,
that is, to those portions of the annulus between RA, Decl = 26, +21
and 43, +27, and between 86, +33 and 106, +22 degrees.

This localization may be improved, but a small error box cannot be
derived for this event.
