Abstract	We recently discovered a unique radio-loud AGN, Speca, the optically dominantmember of a small cluster at z=0.137. Speca is the second spiral-host largeradio galaxy and also the second radio galaxy with three pairs of lobes. Theoutermost, relic lobes, separated by ~1.3 Mpc, show an unexpectedly flat radiospectral index and a high fraction of linear polarization. These suggestlarge-scale shock-like dynamical processes acting in the cluster outskirts. Fromthe distribution of member galaxies we rule out a cluster merger and areinvestigating the possibility of accretion (shock) from filaments. We wish toimage the cluster environment of Speca with XMM to understand the AGN-clustereco-system as it evolves via accretion, merger and feedback processes.

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.
