   Only very recently has A3627 been recognized as a very important
   nearby galaxy cluster (with z =0.016). ROSAT observations imply that
   it is the sixth brightest cluster in X-rays. This object was
   overlooked in all X-ray studies previous to ROSAT because of its
   location close to the galactic plane. For an accurate mass
   determination spectral data from an ASCA observation are required.
   Because of the proximity and the prominence of the cluster, precise
   information on the mass of the cluster is important for the modelling
   of the local Universe. The ROSAT image shows that the cluster is
   currently in a state of a collison of a smaller cluster component
   with the main part. The study of the temperature variations in A3627
   will help to understand the heating of the intracluster gas by
   mergers.
