PV- We plan to use the observation of this narrow line Seyfert 1 galaxy toverify the capability of the RGS to separate and characterize the variouscomponents in its soft X-ray spectrum; this object has a steep power lawcontinuum with a soft excess. It has shown evidence for absorption by ionizedoxygen which suggests the presence of a dusty warm absorber, and for rapidvariability. We will assess the accuracy achievable in deriving its physicalparameters (ionization stages, densities, gas velocities, etc.) over time, andalso demonstrate the feasibility of searching for emission features (inparticular OVIII Ly alpha) from the warm absorber.

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.
