   Coma is a typical relaxed no X-ray dominant regular cluster, which is
   a member of nearest super cluster(Coma-A1367) from our galaxy. From
   the previous observations of EXOSAT, Tenma & Ginga, existence of
   temperature gradient was detected. In recent observation of ROSAT,
   merging structure was observed. Using ASCA instrument, we can make
   imaging observation in the high energy band(up to 10keV) and
   spectrosopy of good quality by large effective area of ASCA XRT. Large
   extended emission of sevral degree forces us sevral pointing
   observation around the main cluster. Here I propose 6 pointing
   observations which include sub-cluster and theenvironments.
