We will observe the cluster pair A2061-A2067, which show evidence for mergeractivity within and potentially between them. Our Chandra observation of thecenter of A2061 shows evidence for a merger with a subcluster just after firstcore passage. There is a shock, and a plume to the NE which is probably the coolcore gas from the merging subcluster. Our radio observations have detected abright radio relic to the SW of A2061, a central halo/relic, and a possiblerelic to the N of A2067. A pair of XMM observations will be used to determinethe properties of the shock in A2061, the dynamical state of this cluster, andthe merger history of A2067. We will search for X-rays near the position of theSW relic and for a filament of intercluster gas in the Cor. Bor. supercluster.

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.
