We propose to perform (as a ToO) a series of 4x10ks+2x40 ks jointXMM-Newton/NuSTAR observations (spaced by a few days) of a microquasar duringits outburst decline phase to follow its broadband X-ray spectral evolution withan unprecedented precision. We will perform simultaneous radio, optical and IRobservations to observe the reactivation of the jet. This will allow us i) tocarefully investigate the physical/geometrical changes of the disc/corona systemthrough the transition and ii) to reveal the drivers of thequenching/reappearance of the jets during the state transitions and how theyconnect to the properties of the accretion flow.

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.
