SGR 1900+14 is the only confirmed Soft Gamma Ray repeater which, due tovisibility constraints in the previous AOs, has not been observed withXMM-Newton. We propose a 50 ks long observation to study its spectrum, searchingfor possible spectral features, and energy-dependent pulse profiles. Thisobservation will provide a set data directly comparable with the existingXMM-Newton observations of the other SGRs (and AXPs).

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.
