We request Target of Opportunity (ToO) observations to study a (new or known)Black Hole (BH) transient in two distinct spectral states (200 ks each or aminimum of a full orbit) simultaneously with two XMM-Newton observations (10 kseach) and multi-wavelength campaigns. BH transients sporadically appear anddisplay complex spectra and fast time-variability properties. Our goal is towitness their evolutions and connections to radio/Opt/NIR properties tounderstand the accretion/ejection processes. Using INTEGRAL simultaneously withXMM-Newton and ground-based facilities, we aim to measure in detail the spectralvariations and correlate them with disc and jet evolutions. Such multiwavelengthobservations are the most fruitful way forward to constrain distinct models.

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.
