A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL
SPI-ACS GRB team, report:

This 15 s long burst was observed by Mars Odyssey (HEND), Konus-Wind,
HETE-FREGATE (H2804), and INTEGRAL (SPI-ACS) at 11172 s.  We
have triangulated it to an annulus centered at RA, Decl (2000) =
342.999, -14.452 degrees, whose radius is 42.983 +/- 0.090 degrees (3
sigma).

This annulus may be constrained and/or improved, but as this event was
not observed by Ulysses due to a DSN antenna problem, a small error box
cannot be obtained for it.
