   In the region that is the link region of ABELL399 and ABELL 401, we
   found the excees emission of hot gas with ASCA. This will be the
   first evidence of interaction among clusters of galaxy. In order to
   study the super cluster in more detail, we propose to observe the
   link region between ABELL3391 and ABELL3395 with ASCA. The system of
   A3395 and A3391 has similar scale to the system of A399 and A401, and
   has the group galaxy with extraordinary large velocity dispergion in
   the link region, so there is a great possibility of interaction among
   the clusters. We open the new field of 'super cluster study'.
