We propose a deep observation of a type Ia SNR in the LMC, serendipitouslydiscovered at high off-axis angles in the XMM-Newton survey of the LMC. Itappears to be one of the most evolved type Ia SNR. A deep on-axis observationwill provide key information in the study of type Ia SNe and their progenitors,and help us to understand the latest stage of a remnant. We will be able torefine the measurement of the mass of Fe present in the remnant, and probe theprogenitor.s circumstellar medium. Improved X-ray images will enable the searchfor a surviving companion, and the study of the distribution of ejecta,revealing possible asymmetries of the SN explosion. Finally, a faint X-ray shellcan be detected, providing measurement of, or limits on, the age of the remnant or ambient density.

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.
