(a) Polar projection of Saturn’s southern aurora obtained with the FUV channel of UVIS on-board Cassini on DOY 21, 2009. Noon is to the bottom and dusk to the right. The grid shows latitudes at intervals of 10° and meridians of 40°. Arrows indicate the main emission and the bifurcations of the main auroral emission. Adapted from Radioti et al. (2011b). (b) Polar projection of Saturn’s aurora obtained with the HST on day 95, 2013. Noon is to the bottom and dusk to the right. A grey 10° × 10° latitude-longitude grid is overlaid. Arrows show bursts of emissions indicative of reconnection of lobe flux in the magnetotail. Adapted from Nichols et al. (2014).
