Abstract	We propose to observe the bright Seyfert 1 galaxy NGC 5548. This well-studiedobject has an X-ray spectrum consisting of a powerlaw, soft excess,warm absorber and reprocessed X-ray spectrum. Using the RGS data we willstudy the absorption and emission spectrum from the warm absorber, inparticular we want to detect the O VIII Lyman alpha line. These data willbe supplemented by the EPIC data that allows an accurate determination ofthe broad-band continuum radiation as well as the iron-K emission andabsorption complexes.

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.
