Abstract GT-The activity of 47 Cas with about 1000 times the Sun.s X-ray luminosity isattributed to a one-solar-mass companion to the optically visible F star. Thesystem very young. Frequent flares are detected in the X-ray light curve. Thistarget is part of a study on the Sun in Time. on the decline of the coronalactivity of a solar analog with time. Important aspects are the emission measuredistribution, the abundance pattern that might be activity dependent, and flarevariability studies with respect to temperatures, abundances, densities, andmass motions. The pn camera and one MOS will be used in TIMING/medium filtermode. Coordinated radio observations with the VLA will be requested.

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.
