Abstract:
Saturn’s aurora reveal the connection between its magnetosphere and atmosphere. Both the intensity and location of the aurora are dependent on the ‘planetary period’ oscillations which are prevalent in Saturn’s magnetosphere. We show observations from recent multi-instrument auroral campaigns demonstrating these dependences and how they are affected by large-scale magnetospheric dynamics such as solar wind compressions.
