Abstract

In 2004 October and November we observed the black hole candidate four times with XMM-Newton's EPIC-pn camera and simultaneously with the Rossi X-ray Timing Explorer (RXTE) and INTEGRAL. We present preliminary results on the analysis of the X-ray spectrum and on the source variability, presenting the highest signal to noise ratio data of the Fe Ka region of the source ever obtained.
