We propose observations of the southern disk of M31, which will, together withour AO14 observations of the northern disk, yield a deep full-coverage map ofthe hot ISM of the star-forming disk of M 31 on sub-kpc scales out to a radiusof virgul10 kpc. The southern disk hosts the intriguingly large stellar associationNGC 206 in the major ring, where it was most likely disturbed by an encounterwith the satellite galaxy M 32. New deep observations will enable us to 1) studythe morphology as well as temperature, density, pressure, and filling factor ofthe hot ISM, in particular around NGC 206 and 2) probe the X-ray sourcepopulation differences associated with the M 32 interaction by obtaining acomplete sample of X-ray sources down to the confusion limit of a few 10^34 erg/s.

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.
