Timing analysis of the INTEGRAL -IBIS and Swift -BAT light curves of the Supergiant Fast X-ray Transient ( SFXT ) IGR J16465–4507 has identified a period of 30.32 \pm 0.02 days which we interpret as the orbital period of the binary system . In addition 11 outbursts ( 9 of which are previously unpublished ) have been found between MJD 52652 to MJD 54764 , all of which occur close to the region of the orbit we regard as periastron . From the reported flux outbursts , we found a dynamical range in the interval \sim 30-80 . Although in this regard IGR J16465–4507 can not be considered a classical SFXT for which typical dinamical ranges are > 100 , still our reported values are significantly greater than that of classical persistent variable supergiant HMXBs ( < 20 ) , supporting the idea that IGRJ16465–4507 is an intermediate SFXT system , much like few other similar cases reported in the literature .
