Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS                      
  Title: THE VERY UNUSUAL CLUSTER A514                                                   


Abstract:
 We propose an observation of the cluster A514 which shows a highly unusual
 morphology in its X-ray surface brightness distribution, has a very low X-ray
 luminosity for its optical richness, exhibits extensive substructure in both its gas
 and galaxy distributions and has an unusually high number of associated radio-tail
 galaxies. This cluster is a very strong candidate for an on-going merger of
 subclusters and an Asca observation provides us with an excellent opportunity to
 study in detail the very early stages of such a merger.
