Abstract	SGR0526-66 was the first soft gamma repeater (SGR) to emit a giant flare,suggesting the existence of magnetars, i.e. neutron stars powered by the decayof their extremely strong magnetic field. Since then, very little informationhas been obtained on this object, mainly because it is the most distant SGR andit has been burst inactive since 1983. However, its persistent X-ray luminosityis surprisingly as high as that of the most active SGRs. We propose to observeSGR0526-66 for 60 ks with XMM in order to get a good quality spectrum andmeasure its pulsation period. These results, compared to those obtained in 2000and 2001 with Chandra and XMM, will allow us to check wether the long lastingnon-bursting state of SGR0526-66 is characterized by a stable X-ray luminosity, spectrum and period derivative.

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.
