We propose a 100 kilosecond observation of the Local Group dwarf spheroidalgalaxy in Ursa Minor taken as 10 monitoring observations of 10 ksec each. Thisshould detect all sources brighter than about 3E33 ergs/sec, giving a goodcensus of X-ray binaries and also place strong constraints on whether anintermediate mass black hole might be associated with the bright radio sourcenear the center of this galaxy.

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.
