Konus - Wind, Mars Odyssey - HEND, and HETE - FREGATE observed
this ~4 s long GRB at 07488 s.  We have triangulated it to a
preliminary annulus centered at RA, Decl (2000)= 171.881, +4.499
degrees, with radius 58.501 +/-  0.403 degrees (3 sigma).  In
addition, the Konus ecliptic latitude response limits the arrival
directions to ecliptic latitudes above 50 degrees, that is, to
that portion of the annulus between RA, Decl=163, +63 degrees
and 226, +35 degrees.  

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