We propose XMM-Newton observations of three newly discovered supernova remnants.With the data we will be able to explore these objects in detail in the X-rayregime. We can measure their spectral characteristics (e.g., temperature,abundance), pinpoint details of their morphology and determine their expansionvelocity as well as estimate their age and distance. The proposed targetsG64.0--0.1 and G83.2+6.9 show radio shells. The southern target G312.4+4.8 has amatch both in the infrared and optical regime. By analyzing the three sources atthese wavelengths we were able to identify them as supernova remnants. Therequested XMM-Newton data will therefore be of high r^ance to complement theobservations, which we performed at other wavelengths.

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.
