Report from Aurora, Torus, Magnetospheres Discipline

   Most activity in the past year has been on the Saturn system, with the
continued activity on Cassini and supporting observations.  Cassini
continues to return excellent data, and as time goes on the science teams
are finding more time to work on their data.  The publication of the
Saturn and Titan books has produced fairly coherent pictures of the state
of the Saturn system, with which new data can be compared.  For remote
observations, there have been continuing HST observations, and 2 new
Saturn programs accepted for the next cycle, PI's are Nichols and Gerard.
The Nichols et al. program will go for 3 years, and several new papers
based on HST data have been published.  We are updating the IOPW web site
to include the most recent pub's.  There have also been ground-based IR
H3+ observations, mainly from T. Stallard and his group.  For Saturn's
aurora, one highlight is the detection of an Enceladus auroral footprint
from Cassini UVIS data (Pryor, Rymer, et al.), with a paper under review
at Nature.  The internal clock of Saturn continues to change time, and the
final explanation eludes us.
