Abstract	The solar corona evolves on time scales of days to years reflecting local andglobal solar magnetic variations. The changes in coronal activity are observedthrough temperature and abundance variations over these time scales. Coronae ofother stars are believed to be analogous to that of the sun, but can be ordersof magnitude more active. Despite the assumed similarity, we are lacking asystematic study of the evolution of a stellar corona on the r^ant time scaleof days. We propose to carry out iso-phase snapshots of the active corona of EIEri over six days in order to study for the first time the chemical and thermalevolution of active regions on a stellar corona over the time scales typical ofevolving solar coronal loops.

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.
