Abstract	XMM-Newton observed SGR 1900+14 in September 2005, after almost three yearsduring which no bursts were detected from this SGR. The flux was a factor 2dimmer than the typical value, but the long term fading of the persistentemission has been interrupted by the recent burst reactivation of the source, asshowed by a XMM-Newton TOO carried out in April 2006. We propose to perform a 50ks observation to constrain changes in the spectrum, pulsed fraction and lightcurve profile, which are expected in a scenario in which the effects of atwisted magnetosphere are considered, and to establish whether the flux hasreached the unexpected low level suggested by recent Swift snapshotobservations.

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.
