We propose a 90ks XMM--Newton observation of the Narrow Line Seyfert 1 galaxy RE1034+396. This has the strongest soft X-ray excess ever seen in an active galaxy(AGN). It also has extremely low absorption in the line-of-sight, so hasexcellent FUSE/EUVE/HST data to delineate the lower energy extent of the softX-ray excess and especially how this connects onto the accretion disc emission.RE1034+396 thus represents the extreme of the NLS1 population, and the best hopefor constraining the nature of the soft excess.

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.
