| Abstract | We propose a ToO observation of the highly variable Seyfert galaxy NGC 2992 withXMM-Newton for 250 ks. The pointing will be triggered by Swift-XRT to catch thesource during its bright flux state. Even though the source has been extensivelyobserved by all major X-ray satellites, its high flux state is still poorlystudied. The time behavior of the iron line is very interesting, suggesting thepresence of a relativistic component which becomes more extreme at high fluxlevels. In addition, an outflow component has been found in the recent NuSTARspectrum and confirmed by a re-analysis of the 2003 XMM observation. We aim atinvestigating the spectral evolution of the accretion disk features in the highstate, on a time scale of a few hours. |

| 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. |
