The possible sources of magnetic field variations in the magnetosphere, the precipitation of energetic particles, and auroral emissions are investigated using magnetic field observations from the GOES 5, GOES 6, AMPTE/CCE, and Viking satellites and a ground station. An analysis of the observations supports the view that the magnetosphere often varies in a periodic way because of its own resonant processes and processes driven by the solar wind. UV images from Viking are used to examine the patterns of precipitating particles in the lower ionosphere.
