CC Eri is a binary flare star, with a short orbital period of 1.56 days.Previous observations have shown it to be variable at optical, UV, radio andX-ray wavelengths. We propose to observe CC Eri with both the X-ray instrumentsand the Optical Monitor to investigate the thermal structure of the corona, bothduring quiescent periods and during the occurrence of any flare. Time-dependentspectroscopy will be used to look for variations in elemental abundances,densities and emission measures during flares, to be compared with solar flares.Flare decay profiles will be modelled to determine loop lengths and reconnectionrates.

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.
