Juno-UVS Views of the Average Jovian Aurora and its Variability

Using high-spatial resolution UVS data from over forty different Juno perijoves, we have made average (and variance) maps for the northern and southern auroras of Jupiter, for a range of sub-solar longitudes. While the auroral brightness and color ratio maps for individual perijoves can be strikingly different, the average maps allow features that are nearly always present, but are relatively faint, to stand out. In contrast, variance maps highlight structures which are much brighter but happen more rarely. Here we examine how the typical Jovian aurora varies with time and local time, and extract the relative brightness between the northern and southern auroras.
