The passage of an ionization front trough a dense molecular cloud can triggerstar formation in the region. The efficiency of the mechanism of star formationis found to be on the order of a few percents in some giant molecular clouds,but very little is known about the star formation efficiency and lifetimes ofshock-induced star-forming regions. We propose to observe the cometary cloudLynds 1622, where star formation has been likely induced by the interaction ofthe cloud with the Ori OB1 Association ionization front. Our aim is to determinethe efficiency of star formation in this cloud through the robust determinationof the stellar census of the region.

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.
