We propose a 50 ksec EPIC observation on Blanco 1, a metal rich high latitude open cluster, that for its characteristics is well suited to address somequestions unsolved by previuos X-ray missions.Our objective is to determine the X-ray luminosity of late type cluster members aiming to understand how metallicity affects stellar magneticactivity and its time evolution. The achieved sensitivity will allow us also to determine the low-mass end ofthe Initial Mass Function of Blanco 1, that for its peculiar origin could be very different from that of other more typical open clusters andstar formation regions.

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.
