Description XMM-Newton observed SGR 1900+14 in September 2005, after almost three years during which no bursts were detected from this SGR. The flux was a factor 2 dimmer than the typical value, but the long term fading of the persistent emission has been interrupted by the recent burst reactivation of the source, as showed by a XMM-Newton TOO carried out in April 2006. We propose to perform a 50 ks observation to constrain changes in the spectrum, pulsed fraction and light curve profile, which are expected in a scenario in which the effects of a twisted magnetosphere are considered, and to establish whether the flux has reached the unexpected low level suggested by recent Swift ..snapshot. observations.

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.
