A new X-ray transient has been detected by the IBIS/ISGRI telescope on
board INTEGRAL during an observation of the galactic center on 2005 Oct. 6-7.
The new source was observed at RA=261.72, DEC=-47.622 (3.8 arcmin error)
with a sigma of 6.7 and a flux of about 11 mCrab in the 20-40 keV band.
In the 40-80 keV band the source is not detected with a 3-sigma upper limit of
about 8 mCrab. The source was always outside of the JEM-X field of view.
The transient was not visible in a previous observation of this region six
days earlier.
ATel #623 has just been issued during the submission process of this one
reporting a new transient source XTE J1726-476 at 6.3 arcmin from
IGR J17269-4737. The two sources might be the same.
We encourage follow-up observations of this source at all wavelengths.
