Abstract	Investigations of the relationship between stellar magnetic activity androtation reveal the presence of a saturation threshold where, for unknownreasons, activity no longer varies with rotation period (Prot). However, thesestudies have focused on stars in young open clusters (<500 Myr) and field stars(2-10 Gyr). Measuring Prot and proxies for magnetic activity in older openclusters is essential to understand the evolution of the activity-rotationrelation from the ZAMS to the age of field stars. We propose a snapshot surveyto complete the X-ray census of stars with measured Prot in the 650-Myr-oldHyades. By matching the resulting X-ray catalog to our catalog of 90 HyadesProt, we will analyze the behavior of coronal activity as a function of Rossby number Ro at 650 Myr.

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.
