Abstract	We propose a sensitive XMM-Newton survey of the grand-design Scd face-on spiralgalaxy NGC 6946. This galaxy is remarkable due to its high star formationactivity (e.g. the high number of recorded supernovae), its massive peculiarnorthern spiral arm and radio detected magnetic arms. located between theoptical arms. XMM-Newton will be used to disentangle and characterize emissionfrom point sources and extended hot gas. These observations will also be used tofurther investigate the puzzling origin of the ultra-luminous emission complexMF16.

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.
