Abstract	The present program to study solar-like cycles in the X-ray emission of starssimilar to our Sun has been ongoing since AO-1.Five targets in three stellarsystems have been monitored since 2001, providing clear evidence of long-termcycles in the X-ray luminosity of normal stars, with variations in X-rayluminosity of up to an order of magnitude. The present proposal requestscontinuation of the ongoing monitoring program into XMM AO-9, needed to progresstoward full characterization of the coronal cycle for our targets.

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.
