Abstract:
The gas giant Jupiter possesses a strong internal magnetic field that 
produces the largest magnetosphere in our solar system and leads to 
spectacular auroral emissions. Eight spacecraft have now visited the 
Jovian system, yielding a wealth of information about Jupiter’s 
rotation-dominated magnetosphere and its internal plasma source, the 
volcanically active moon Io. The Galileo spacecraft, which was in orbit 
around Jupiter from 1995 to 2003, has provided the most extensive 
spatial coverage of the magnetosphere and the opportunity to study 
temporal changes on long time scales. In this talk I discuss the dynamic 
nature of Jupiter’s magnetosphere and aurora, using both in situ 
spacecraft measurements and Earth-based telescope observations to 
illustrate changes on time scales from days to several years. I will 
focus on recent work in which we characterize long-term changes in 
Jupiter’s magnetic field configuration due to current sheet variability 
and will discuss the resulting implications for the aurora. Finally, I 
will consider the relative roles of the solar wind and internal factors, 
such as rotational stresses or changes in Io’s plasma production, in 
driving the many temporal variations in Jupiter’s magnetosphere.
