| Abstract | We propose an 80 ks (4 x 20 ks) observation of the Sgr A complex to address twodifferent topics. First, to continue monitoring the Fe K-alpha emissionvariability in the Galactic center due to the interaction of molecular cloudswith a 200-years-old energetic flare from Sgr A*. This study will allow us tobroaden the description of the distribution of the molecular clouds in the innertens of parsecs of the Milky Way. Second, to investigate the current flaringactivity of Sgr A* with simultaneous observations with GRAVITY. In this case, weencourage the observations to be taken simultaneously with GRAVITY observationsof Sgr A*. This will allow us to combine the information about the particleacceleration coming from XMM-Newton with information about the dynamics from GRAVITY. |

| 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. |
