Type Ia SN 2003lx was first discovered in X-ray through two serendipitous Swiftobservations in 2008 January and the corresponding merged image revealed a7-sigma source detection at 2.1+/-1.2 arcsec (0.9+/-0.5 Swift pixels) from theopticalposition of the supernova. We propose a XMM-Newton observation of Type IaSN 2003lx to study its flux and spectral properties. If confirmed, SN 2003lxwill be the first concrete X-ray SN Ia detected. The X-ray emission will thenallow us to probe the interaction between the fast moving debris of the explodedstar and the circumstellar medium (CSM). This in turns provides footprints ofthe mass-loss history of the exploded system, and may allow us to learn aboutthe nature of the progenitorand its companion.

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.
