Results are reported for Ariel 5 X-ray observations of Zwicky cluster No. 7, a supercluster containing the three rich Abell clusters of galaxies A2151 (the Hercules cluster), A2152, and A2147. Six detections with the Sky Survey Instrument are shown to be consistent with the presence of a single source, designated A1600+16, having a steady intensity level of about 0.7 Ariel count/sec. This source is tentatively identified with cluster A2147, and the X-ray, optical, and radio properties of A2147 and A2151 are compared. It is suggested that the observed X-rays originate from a hot intracluster gas.
