The position of the new fast X-ray transient IGR J17464-2811 (ATEL
#970) is consistent with that of the transient XMMU J174716.1-281048
which was active during XMM-Newton observations of this region
performed on February 26-27, 2005 (Sidoli et al. 2006, A&A 456, 287).
The positional coincidence as well as the closeness in time of the
INTEGRAL and XMM-Newton observations strongly indicate that both
satellites detected the same transient source. The XMM-Newton
position of this source as listed in the Sidoli et al. paper is RA =
266.817367 deg, Dec = -28.180065 deg (J2000; with an error of
approximately 4 arcseconds). This transient source has been previously
detected with XMM-Newton on March 12, 2003, but could not be detected
during observations on September, 23, 2000 (indicating X-ray fluxes of
at least 80 times lower; ATEL #147). The transient nature of the
source combined with the likely detection of a type-I X-ray burst with
INTEGRAL (ATEL #970) strongly suggest that this source is a
transiently accreting neutron-star X-ray binary likely with a low-mass
companion star.
