The observations began when the source was still relatively bright, and, during one of the early observations, a QPO with a non-Lorentzian profile occurred near 6 Hz. As the source decayed, the X-ray flux dropped exponentially with an e-folding time of 14.4 d. The exponential decay was interrupted by an increase in the X-ray flux, and a secondary maximum occurred 89 d after the onset of the outburst. A transition marked by signific","authors_text":"John A.
