We propose 4 observations of one high inclination black hole low mass X-raybinary (LMXB) at different stages of its outburst. We will investigate thepresence of X-ray narrow absorption/emission features in the XMM spectra, whichare a signature of a disc wind, and their relation to the accreting regime. Suchfeatures, identified with ions like FeXXV and FeXXVI, have been observed in anumber of LMXBs and give us information about the mass outflow rate and thelaunching mechanism of the wind. With simultaneous radio observations we willprobe the jet power as a function of the wind properties and how the radio fluxdensity correlates with the X-ray flux at different accretion regimes. We willalso investigate the broadening mechanism of the FeK emission line detected up to now in several LMXBs.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
