Description In December 2004 SGR 1806-20 emitted the most powerful giant flare ever observed from a Soft Gamma-ray Repeater. This probably involved a large scale rearrangement of the magnetosphere leading to observable variations in the properties of its persistent X-ray emission. Comparison of the pre- and post-flare observations supports the model of a magnetar with a twisted magnetosphere. We are studying the long term effects of the Giant Flare and the source evolution after this ''once-in-a-lifetime.. event with a long term XMM-Newton and INTEGRAL monitoring of SGR 1806-20. Based on the trend seen in the latest observations (performed every six months), we estimate that the sampling frequency can now be reduced and therefore, we require only a single pointing during AO9.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
