GT-The X-ray and ultraviolet light curves of X1822-371 will be measured overthree 5.57 hour binary cycles in order to study the relationship of theaccretion disk corona to the disk, and to measure the disk geometry. The X-rayspectrum of the source will be measured as a function of the binary phase,making use of the phase dependent obscuration of the accretion disk corona toseparate different spatial components of the emission.

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.
