Abstract
Excellent coverage of the 1998 outburst of the X-ray nova XTE J1550-564 was provided by the Rossi X-Ray Timing Explorer (RXTE). XTE J1550-564 exhibited an intense (6.8 crab) flare on 1998 September 19 (UT), making it the brightest new X-ray source observed with RXTE. We present a spectral analysis utilizing 60 Proportional Counter Array spectra from 2.5-20 keV spanning 71 days and a nearly continuous All Sky Monitor light curve. The spectra were fitted to a model including multicolor blackbody disk and power-law components. XTE J1550-564 is observed in the very high, high/soft, and intermediate canonical outburst states of black hole X-ray novae.Keywords
