SAX J1748.2-2808, discovered with BeppoSAX in the Galactic Center (GC) region,is of particular interest due to the presence of a remarkably intense iron linewith EWvirgul1 keV. It is located in the field of the molecular cloud SgrD and ispositionally coincident with an IRAS source. The nature of SAX J1748.2-2808 isuncertain and its very intense Fe K line emission, together with its highlyabsorbed spectrum,made it an unique object in the GC region. On the other hand,very recently the INTEGRAL satellite has discovered other objects similar toSAXJ1748.2-2808, with a highly absorbed spectrum and intense iron emission, likeIGR J16318-4848. The proposed observation can discriminate between differentpossible origins for the X-ray emission from SAXJ1748.2-2808.

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.
