XMM-Newton follow-up observation of the transient source IGR J16465-4507
detected by INTEGRAL on Sept. 6, 2004 (ATEL#329) was performed on Sept. 14, 2004
(02:16-04:45 UTC). A single counterpart is detected with the EPIC/MOS camera
at position RA=16:46:35.5 DEC=-45:07:04 (J2000, uncertainty 4").
The X-ray flux (3+/-1)E-12 erg/sec/cm2 (4-10 keV) is about 100 times fainter
than during the flare detected by INTEGRAL on Sept. 7.
A bright infrared counterpart (2MASS J16463526-4507045, J=10.54) is found in
