Abstract
The results obtained from the ASCA observations of the cluster of galaxies Abell 3627 are presented. This cluster, located behind the Milky way, was recently found to be a nearby, X-ray bright and very rich cluster. Pointed observations onto the central region of the cluster gave a gas temperature of
∼7
keV and a metallicity of about 0.2 solar. An offset pointing to a substructure elongated to south-east of the cluster center gave a significantly lower temperature of
∼5
keV. The 2--10 keV luminosity within a radius of 40' (1.1 Mpc) is estimated to be
3.7×
10
44
erg/s
. The X-ray data imply a cluster mass of about
4×
