Abstract	The space density of the most powerful absorbed AGN (QSO2) and theircontribution to the AGN luminosity output remains uncertain. Many of theseobjects are severely attenuated, so hard X-ray surveys alone do not fully provethe bulk of the obscured QSO population in the nearby Universe. We propose a 80ksec XMM-Newton observation of an optically selected QSO2 at z~0.1. Comparingits OIII and 2-10 keV luminosities the source is likely a Compton-thick AGN.However, the X-ray spectral analysis seems to indicate that it might be insteadCompton thin and X-ray weak. The proposed observations will allow us to unveilthe true nature of this source and will give us key information on whetherobjects such as this are intrinsically different to the QSO2 population detected in hard X-ray surveys.

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.
