Abstract
Following reports of bursting activity of IGR J17473-2721 (= XTE J1747-274) by the AGILE team (Del Monte et al., ATEL #1445) and from Swift (Altamirano et al., ATEL #1459), we note that RXTE PCA monitoring scans of the source also reveal persistent activity. Scans on 2008-03-28 at 18:50 UT and 2008-03-31 at 15:10 UT found 2-10 keV fluxes of about 13 and 18 mCrab, respectively. Previous scans are consistent with quiescent level (with 2-sigma upper limits ~6 mCrab).
