[en] The in-situ exploration of the magnetospheres of Jupiter and Saturn has revealed various pulsed phenomena, some of them being periodic. In Saturn’s magnetosphere, several studies have reported pulsations with a periodicity of around one hour in the measurements of charged particle fluxes, plasma wave emissions, magnetic field strength and auroral emission brightness. A Cassini multi-instrument overview of these hourly pulsations will be presented. A survey of the quasi-periodic 1-hour energetic electron injections observed in Saturn's outer magnetosphere has been achieved together with an analysis of simultaneous pulsations in the low-frequency radio emissions and in the magnetic field. Quasi-periodic 1-hour brightening of auroral structures associated with magnetopause reconnection has been also reported. Pulsed high-latitude lobe reconnection is a likely common triggering process for brightening of a polar auroral spot associated with the cusp and the high-latitude electron pulsations. Finally, the involvement of magnetopause reconnection in the generation of the quasi-periodic electron injections will be discussed.
