****************************************************** PR # 41214 We propose to observe four clusters of galaxies in the Shapley supercluster which is the richest supercluster in the local universe. A3562, SC1329-313, SC1327-312, A3558 are candidates for interacting clusters since their separation and relative velocities are only 1Mpc and 700-1000km/s. We take in total four images from A3562 to A3558. Main purpose of mapping observations is to make clear the formation and evolution process of the clusters of galaxies in a supercluster. The observation will give essential information on the formation of large scale structures, baryon distribution and galaxy formation process in a supercluster region, both of wich are important issures in observational cosmology. ******************************************************
