We propose to observe a full binary orbit of the eclipsing magnetic cataclysmicvariable V1309 Ori with XMM. The soft X-ray flux of this system is highlyvariable on time scales down to seconds and V1309 Ori is, therefore, an idealtest case to confront the theoretically established concept of blobby accretionwith observational data. With XMM we will for the first time receive enoughphotons to determine the spectral and temporal characteristics of the X-rayemission produced by the penetration of individual accretion blobs into thewhite dwarf photosphere. In addition, the orbital and eclipse light curves willbe used to determine the structure, extent, and location of the accretion

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.
