Kilometric continuum radiation is a non-thermal magnetospheric radio emission. It is one of the fundamental electromagnetic emissions in all planetary magnetospheres [cf. the review by Kaiser, 27]. We review its observational properties in view of their agreement with theoretical models. Although this emission has been observed and studied for more than 35 years, there are still several unveri fied theories on how this emission is generated. It is by now quite certain that it is emitted from the plasmasphere, in particular from the plasmapause and from density notches and cavity gradients. Mode conversion at density gradients plays an important role. Observations show that the radiation consists of a magnetospherically trapped and an escaping component. It exhibits a narrow-band fine structure that is barely understood, but beaming models can be safely excluded based on the observations of the frequency-time structure of the radiation. We investigate its relation to geomagnetic activity and solar activity.
