The observations were carried out at a typical rate of once or twice per day. The source shows interesting spectral evolution during this period. Phenomenologically, it bears remarkable similarities to ``atoll'' sources. Shortly after the onset of the outburst, the source is seen to be in an ``island'' state, but with little X-ray variability. It then appears to have made a rapid spectral transition (on a time scale less than half a day) to another ``island'' state, where it evolves slight","authors_text":"(2) CESR, (3) MSFC, (4) GSFC), Didier Barret(2), Jean Swank (4) ((1) MIT, Laurence Boirin (2), S.
