We propose simultaneous observations of the ultrafast rotating late-type starSpeedy Mic at X-ray, near UV and optical wavelengths. In this way we want tostudy the spatial correlation of coronal, chromospheric and photosphericactivity phenomena. The proposed study includes time-resolved high resolutionspectroscopy monitoring of key line ratios, probing the distribution of coronaltemperatures, densities and elemental abundances.The requirement of strictlysimultaneous observations results from the short-lived nature of active regionson Speedy Mic. Our proposal is based on our previous results from VLTmeasurements constructing a Doppler image of Speedy Mic and finding pronouncedrotational modulation of CaII emission.

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.
