GT-AT Mic is an X-ray luminous M dwarf binary system, consisting of two almostidentical flare stars. Energetic flares have been observed previously. Wepropose to observe AT Mic to investigate its abundance and temperaturestratification, and search for temperature dependent densities and abundances.Small-scale flare variability will be looked for, and larger flares will beanalyzed in terms of temperature, density, velocity, and abundance historieswith the RGS and the EPICs. Simultaneous radio VLA/VLBA observations will berequested to investigate flare energy release. One EPIC MOS and the pn camerawill be operated in TIMING mode with the medium filter to optimize for flares.The OM will use the UVW1 filter.

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.
