IOPW Aurora amd Magnetosphere sub-Discipline Update Nov 2015 The concentration of effort in the past year has again been at Saturn, owing to the continuing Cassini mission and concentration of data taking. The Japanese EXCEED instrument on the HISAKI mission is also operating, and returning observations of the Io plasma torus and jovian aurora. The first science results from EXCEED have also now been published. The status of the discipline was reported at the July 2015 Magnetospheres of the Outer Planets conference, held in Atlanta GA (http://mop.gatech.edu/). The next MOP meeting will be over 12-16 June 2017 in Uppsala Sweden. The main results from the past year are best summarized by the many new publications that have come out, listed below. A good overview of the areas of effort can be gleaned simply from the paper titles.
