We present results of ROSAT/PSPC and HRI observations of the AWM 7 group of galaxies, which is a poor galaxy cluster and forms part of the Perseus-Pisces filament. The X-ray emission originates from intracluster gas at temperatures of 1.7 to 4.5keV. The cluster obviously is elliptical with a position angle perpendicular to the position angle of the dominant elliptical galaxy NGC 1129, which is offset from the cluster X-ray centre by 30kpc. The analysis of the PSPC imaging and spectral data yield a gravitational mass of 2-5x10¹⁴M_☉within a radius of 1.2Mpc and a cooling flow with a mass deposition rate of up to 60-66M_☉/yr.
