Abstract	PG 1244+026 is a an extremely bright active galaxy (AGN) with the narrowestH-beta line among all PG quasars. Its broadband spectral energy distribution(SED) shows a huge soft X-ray excess making this object a perfect test for ourmodels of NLS1 which are dominated by large hot discs. Here we propose toobserve this object in order to study its X-ray spectrum and spectralvariability. A long exposure time XMM-Newton observation will resolve detailedfeatures in its X-ray spectrum and RMS spectrum, especially in the soft-excessregion. This study will help us to understand the nature of the most extremeNLS1s, and provide essential evidence towards the unification of the accretionprocesses between AGN and black hole binaries (BHBs).

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.
