Abstract
We report Swift observations of the transient millisecond pulsar SAX J1808.4-3658 which is currently in outburst. SAX J1808.4-3658 was observed with Swift on 2005 June 16. The source was clearly detected in the X-ray Telescope images and it is bright enough to show significant pile-up in the 787s Photon Counting mode data. We extracted the spectrum from the 119s Windowed Timing data and performed spectral fit.
