Description Observations in the temporal domain open up new windows on astrophysics that snapshot observations simply cannot address. We propose an eclipse timing and rotational modulation observation of the RS CVn system XY UMa to further our investigations of the morphologies of active stellar atmospheres. Earlier eclipse mapping observations have given contradictory results: sometimes the coronae appear compact (solar-like), at other times they appear extended. Uninterrupted observations longer than the stellar rotation period are needed to ensure a view of the quiescent corona amidst the frequent flaring. Observations spanning 3 stellar orbits will reveal the coronal scale heights, latitudes, and spatial scales down to 100,000 km, or about 5% of the stellar radius.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
