SPI-ACS GRB team, report:

Ulysses, Mars Odyssey (HEND), and INTEGRAL (SPI-ACS) observed this
burst at 15952 s.  As observed by Ulysses, it had a duration of
approximately 15 seconds, a 25-100 keV fluence of approximately
7.5E-06 erg/cm2, and a peak flux of approximately  8.0E-07 erg/cm2 s
over 0.25 seconds.

We have triangulated it to two alternate, preliminary, 3 sigma error
boxes each with approximate area 1900 square arcminutes whose
coordinates are:

There is a chance that the ambiguity can be resolved by further processing.
These error boxes may be improved.
