Aurora / Torus / Magnetosphere

The highlight of recent auroral observations of Jupiter and Saturn has 
been the publication of numerous results from an HST large observing
program over 2007 / 2008.  There are more than a dozen papers to date,
and a special session at Fall 2008 AGU on outer planet aurora had 44
submissions.  Much of this work is a combination of Cassini and New
Horizons data sets in comparison with the HST auroral images. 

For the outer planet environments, most new results have come from
the continuing analysis of Cassini data at Saturn.  A good overview
of Cassini results was presented at the summer 2009 Magnetospheres of
the Outer Planets meeting in Cologne:
