Abstract

We report on Rossi X-ray Timing Explorer Proportional Counter Array observations of the accreting millisecond pulsar IGR J00291+5934. The system was detected in outburst on 2008 Aug 13 (ATel #1660), and was subsequently observed in X-rays with Swift as well as in the optical and UV (ATel #1664, #1665, #1666, #1668). The X-ray flux measured by RXTE/PCA was at a maximum during the initial measurements between Aug 13 and 15, of 6.3e-10 erg/cm^2/s (2.5-25 keV; the Crab flux in this band is 3.3e-8 erg/cm^2/s).
