Abstract	Building on the great successes of the monitoring program of Sgr A* flaringactivity we initiated and fostered in the last years, we propose to continueextended observations of the Galactic nucleus with XMM-Newton in order tofurther test the supermassive black hole paradigm while studying the accretionflow and radiation mechanisms associated with this unique system at the centreof the Galaxy. Thanks to the unique capabilities of XMM-Newton we will tacklecrucial questions that remain unanswered: 1) are X-ray flares from Sgr A* causedby blobs of hot, orbiting plasma in the accretion flow close to the eventhorizon of the black hole,

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.
