| Abstract | Several aggregates in the high galactic latitude molecular cloud (HLC) in theregion of IC2118, the Witch Head Nebula, appear to be forming stars. Starformation (SF) in HLCs, while rare, may be the origin of some of the apparentlyisolated TTauri stars revealed by ROSAT. IC2118 is a very interesting 2 Myr oldHLC located at l=208, b=-28 and at 210 pc. To unveil the true cluster populationwe propose to map three condensations, including as yet undetected Weak-lineTTauri stars. The X-ray data, together with optical and IR observations, willallow to derive for the first time the Initial Mass Function in a SF region athigh latitude, and compare it with regions of different environment and SFhistory. |

| 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. |
