Persistent X-ray activity has been reported by Swift/XRT (ATel #1459) and RXTE/PCA (ATel #1460) from the transient IGR J17473-2721 (= XTE J1747-274; ATels #467, #498) after the detection of an X-ray burst by SuperAGILE (ATel #1445). We report the detection of persistent activity at 18-100 keV with INTERAL/IBIS/ISGRI. The average hard X-ray flux during the Galactic bulge monitoring observations (see ATel #1385) which started on UT 2008 April 1, 16:55 of the source was 41+2 mCrab and 42+3 mCrab, at 18-40 keV and 40-100 keV, respectively, indicating a hard spectral state.
