We will newly examine the magnetic signatures of field-aligned coupling currents in Saturn's magnetosphere observed on highly-inclined orbits of the Cassini spacecraft in 2013 under conditions of northern spring. These will be compared with corresponding data obtained during southern summer to search for seasonal differences. The results will subsequently be input to the development of models of the field-perturbations due to these currents that are present within the Cassini grand finale mission data (2016/17), to help discriminate their signatures from those of rotating internal field asymmetries.

我们将重新研究磁场对齐耦合电流在土星的磁层上观察到的卡西尼号飞船在2013年的北方春天的条件下高度倾斜的轨道上的磁特征。这些将与在南部夏季获得的相应数据进行比较，以寻找季节差异。结果随后将输入到卡西尼号大结局使命数据（2016/17）中存在的这些电流引起的场扰动模型的开发中，以帮助区分它们的签名与旋转内部场不对称性的签名。
