Abstract We propose 50 ksec observations of two of the brightest,unabsorbed but otherwise normal Seyfert 1 nuclei: MCG--2-58-22 andArk 120. We will constrain the intrinsic X-ray continuum with fargreater precision than is possible in other, more spectrally complexobjects and will and test the fundamental assumption that the Seyfertcontinuum is well-represented by a (Gammavirgul1.9) power-law.We will determine the iron line profile parameters, search for signsof soft X-ray reflection features and measure changes in the shape ofthe continuum, free from the ambiguities associated with simultaneouslymodelling the complex absorption present in other bright Seyferts.

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.
