We propose to perform a unique NuSTAR/XMM monitoring with 5 repeatedobservations of 50 ks spaced by a 2-3 days of the extreme Radio-Quiet Narrowline Seyfert 1 galaxy Mrk 359. This will permit 1) to correctly disentangle thedifferent spectral components present in this energy band, and 2) to revealtheir complex interdependences and variability behavior. This study will allowus i) to constrain the physical parameters of the Comptonizing coronaeresponsible for the bulk of the X-ray emission ; ii) to investigate the natureof the soft X-ray excess and differentiate between multiple origins; iii) to putfirm conclusions on the distance, nature and geometry of the reflectingmaterial(s). Such monitorings appear as the best strategy to reach these goals.

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.
