PV- The Coma cluster region over a scale in excess of 1 degree is mapped with aseries of overlapping EPIC images. This observation demonstrates the ability to mosaic large extended structures. A series of 14 overlapping exposures ensuresgood coverage of the Coma cluster region, andallows mapping the temperature ofthe whole region, including the colliding subcluster to the southwest. Theposition angle alignment is fortuitously close to the RGS dispersion directionso that we also examine the ability to measure grating spectra of large diffusestructures, noting the difference between core and wings spectra of the cluster.With OM exposures of most of the cluster we are able to provide for the firsttime a sensitive UV survey of the cluster populations

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.
