Abstract	The aim of this proposal is to verify whether the Lambda Orionis Star Formingregion (LOSFR), composed by several dark clouds in a 10 deg diameter ring, wascreated by a SN explosion coming from the central cluster, or by cloudfragmentation. So far, we have carried out a multiwavelength study of theproperties of three clusters within the region, Coll69 (in the center) and B30 &B35 (in the rim), finding clear evidences of age spread between them. We proposeto image two regions between C69 and B30 to study the radial distribution ofyoung stellar sources from the center to the rim. While a continuous number ofsources would be consistent with a supernova explosion, a clear discontinuitywould point towards cloud fragmentation as the most probable formation scenario.

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.
