The first snap-shot (18 ks) observation of the prototype Narrow-Line Seyfert 1galaxy, I Zw 1, with XMM-Newton revealed a myriad of exciting features:Low-energy spectral complexity; indications for multiple Fe K_alpha lines; and ahard X-ray flare which induced continuum variability, but not emission-line(s)variability. With this proposed 85 ks observation, we will be able to examinethese, and other properties, in much greater detail. The exposure time willprovide sufficient signal to utilise the RGS so that we may study the low-energyspectrum with high-resolution, while the pn will allow us to distinguish betweenvarious interpretations for the line feature(s) at virgul6 keV.

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.
