   During ASCA observation of the distant cluster: CL0107+31, we detected
   a serendipitous source near the cluster(11'off). Observed flux is 1.3E-
   12 ergs/sec/cm^2. Its position is coincident with the radio galaxy,
   NRAO 58, which has never been identified, and whose redshift has not
   been known, too. We found this new X-ray source tends to extend, and
   the spectrum of the center region is harder than that of all region,
   but we could not distinguish between thermal and non-thermal emission.
   Therefore we guess the X-ray emission consists of a point-like radio
   galaxy component and a diffuse cluster component. We want to confirm
   the origin of the X-ray emission, and determine the distance of the
   source.
