Abstract

The authors report 22.2 GHz observations of the quasar 0552+398 (DA 193). The data are used to refine the source structure model and magnetic field estimate previously reported by Spangler and colleagues in 1983. The source is found to be more compact and the magnetic field to be weaker than indicated by the previous observations. It is suggested that the object may be considered a highly compact, "naked core" object.
