Abstract	Chromospheric activity cycles are often found in old stars, but their coronal X-ray counterparts have been difficult to catch. Thanks to XMM-Newton, X-raycycles have been detected in four stars, moving forward an exploration of theparameters space of dynamo cycles (activity level, cycle length, etc.). Twostars with known X-ray activity cycles are relatively young (500Myr), rising thequestion at what age and activity level X-ray cycles set in. We propose here 4short (6ksec) observations of Kepler63. It is younger (250Myr), has higheractivity (logLx=29.02erg/s) and a shorter cycle (1.27yr) that the previoustargets for such dedicated studies. A single XMM-Newton observing season cancover 1/2 of a full cycle with short snapshots.

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.
