The purpose of my research is to examine electric fields, currents, and energy flux associated with different auroral structures, in the auroral acceleration zone. To do this, data from the Cluster Satellites was used. Cluster is a grouping of four satellites that travel together in a tetrahedral formation. Their close proximity allows data to be gathered from multiple sources in one event. Comparing the data from multiple satellites allows one to see how the fields change over time and see different areas of an auroral structure simultaneously.
The auroral structures can be seen using the THEMIS All Sky- Imager. This is a collection of stations, mainly in Canada, which take images of the night sky.
