Abstract	We propose a 100 ks XMM-Newton observation of J1641, a z=6.047 QSO accreting ata super- Eddington rate (lEdd=1.5). Our exploratory Chandra observation of thisobject (~48 net counts) reveals extremely bright X-ray emission, 9 timesbrighter than the expectation based on its UV luminosity, in contrast to ourknowledge of accretion at high Eddington ratio. Thanks to the extremely brightX-ray emission of the target, the new XMM-Newton observation will collect ~400net counts, which is the largest number of X-ray photons for a z>6 QSO, allowingus to constrain tightly the X- ray properties of this QSO, in particular itsluminosity and photon index, and to check for variability.

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.
