| Abstract | Correlated fast multi-wavelength variability is quickly becoming a key tool for studying thephysics of accretion/ejection of relativistic jets. Using X-ray/IR simultaneousdata we have recently discovered vibrations from a relativistic jet down to 62.5ms time scale, which allowed us to estimate the jet speed and size. Our resultsfrom further data also show that the jet properties depend on the spectral stateof the BH. Here, we propose to monitor the outburst evolution of a BH transientwith XMM, simultaneously with ground-based OIR facilities, in order to apply thesame technique to different states. We will monitor the energetic andgeometrical changes in the jet, and its relation with the accretion disk. We propose to perform up to 10 short XMM observations. |

| 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. |
