We propose two 35ksec observations of the Sculptor group galaxy NGC 300 tofollow up on our earlier observations in 2000 December/2001 January. Our aim isto search for and study the long-term luminosity variations of the 30 brightestsources in NGC 300 on timescales from years to months, to push the detectionlimit of X-ray point sources in NGC 300 to luminosities below 1E37 erg/s, toincrease the number of sources which can be studied spectroscopically, and toidentify contaminating background AGN through spectral and variability studies.

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.
