Istanbul), Chryssa Kouveliotou (NASA/MSFC), Tod\nStrohmayer (NASA/GSFC) report on behalf of a larger team:\nRXTE/PCA observed the new source, Swift J1822.3-1606 (Cummings et al. GCN\nCirc. 12159) on 2011 July 16, for 6.7 ks. We performed a timing analysis on\nthe barycentered data and detected a coherent pulsation at 0.1185149(2) Hz\ncorresponding to 8.4377585 s. Pulsations are clearly visible in the PCA\nlight curve. The peak-to-peak pulsed amplitude in the 2-10 keV band is 0.41.\nThis pulsed fraction is highly unlikely from an SGR source, and very\nreminiscent of the outburst onset of Swift J1626.6-5156 (Palmer et al.\n2005), that is likely a Be-X-ray binary system. Alternatively, the source\ncould be similar to the rotation powered PSR J1846-0258 (Gavriil et al.\n2008), which was observed to emit SGR-like outbursts. Further\nmulti-wavelength observations of the source are strongly encouraged to\ndetermine its nature.",
