Abstract	An optical variability study of the benchmark star forming region NGC2264,observed with CoRoT, suggests that the cluster is more extended than currentlybelieved. To confirm this result we obtained, in AO10, a 50ks EPIC pointingtoward the cluster periphery. The observation fully confirms the existence of aspatially extended population. We propose to observe four more fields, each for50ks. Our goals are: 1) establishing whether the clustered and dispersedpopulations originated from the same or distinct star formation events; 2)determining whether mass segregation affects NGC2264, thus compromising currentdeterminations of the IMF; 3) deriving disk frequencies throughout the clusterand in sub-regions with different stellar densities and UV-radiation fields.

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.
