A. von Kienlin, G. Lichti, and A. Rau, on behalf of the
INTEGRAL SPI-ACS GRB team, report:
Konus, Mars Odyssey (HEND), and INTEGRAL (SPI-ACS) observed this
event (GCN 1941). We confirm that this is indeed a gamma-ray
burst. Because the burst arrived along a direction close
to the Konus-Mars vector, the triangulation annulus is imprecise.
It is centered at RA, Decl = 280.256, -23.488 degrees, and
has a radius 11.122 +/- 0.456 degrees. This annulus is consistent
with, but does not constrain, the IBIS localization in GCN 1941.
Ulysses data are expected within 24 hours, and may improve this
triangulation.
