RX J0439.6-5311 is a bright NLS1 galaxy with very low attenuating column densityand very narrow Hb FWHM, small black hole mass and super-Eddington massaccretion rate. It has intriguing soft X-ray spectral shape similar to that inthe QPO AGN REJ1034+396. It also exhibits strong X-ray variability in short andlong timescales. These characteristics make RX J0439.6-5311 a great source forstudying the intrinsic emission from the core region of such extreme NLS1s. Wepropose a long, uninterrupted XMM-Newton observation of this source (1revolution, 120-130 ks), in order to conduct a detailed study of its intrinsicvariability and spectral properties in the X-ray, UV and optical, and provideconstraints to its black hole mass and spin.

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.
