In April and May 2013 the Cassini spacecraft, the Hubble Space Telescope, and a number of ground-based telescopes undertook an unprecedented observing campaign to study the aurora of Saturn, forming the most comprehensive set of remote and in-situ observations of this spectacular interaction between the planet’s atmosphere, magnetosphere, and solar wind. Auroral emissions were recorded in the ultraviolet, visible, infrared, and radio, and a host of in-situ Cassini instruments measured the magnetic field and plasma environment inside the magnetosphere of Saturn, enabling unique synergistic studies of every region of the magnetosphere and planetary atmosphere that form part of this process. We’d like to publish the results of this campaign in a special issue of Icarus.

Topics of interest include:

+ Characterizing the mechanisms that drive auroral processes at Saturn.
+ Comparing simultaneous auroral emission from the northern and southern polar regions.
+ Comparisons between ultraviolet, visible, and infrared auroral emissions, enabling direct comparisons between ionospheric and magnetospheric emissions.
+ Monitoring long term trends in auroral intensity in both hemispheres to isolate seasonal and intrinsic (magnetic field) dependences.
