   SCC100 is the one of the Super Cluster Candidates identified by Batsuki
   et al.(1985). This region contains 29 clusters of galaxies within 3 deg
   radius centered at (347.5,22) and cluster members are distributed in
   the range z=0.17 to 0.23, which corresponds to about 100Mpc deep and
   10Mpc wide. The clusters are in a large scale density structure, such
   as the "Great Wall". Since they were born and have been grown up in the
   same circumstance, they are good samples for studying the evolution of
   initial density perturbation and the cluster evolution itself. ASCA has
   observed SCC100 region at 7 points including 9 Abell clusters and found
   more than 10 new sources. From the previous observations, we can expect
   to observe about 20 X-ray sources in this proposed observations.
