We propose to observe the supernova remnant G347.5-0.3, a second example of a shell-like SNR dominated by synchrotron emission (after SN 1006), but more extreme in the sense that no thermal emission has been detected.Five pointings of 10 ks are required to cover the most interesting regions, namely the four brightest opposite regions in the rim and the interior.Our objectives are to map and diagnostic the synchrotron emission, to measure the unreaveled thermal emission and its properties over the remnant, to determine the unknown nature of the point-like source located at the center of the remnant.

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.
