[en] The Cassini Ultraviolet Imaging Spectrograph (UVIS) has been obtaining Saturn auroral images since 2004. We have previously reported instances when the main auroral oval brightened briefly in a quasi-periodic fashion near the sub-Mimas longitude. Here we examine the large set of UVIS auroral images obtained from close range and high sub-spacecraft latitudes. We will plot the brightness of the individual auroral measurements (and binned auroral measurements) as a function of local time, and as a function of the location of Mimas and other moons to test for any correlations. Mimas, while a relatively small moon, exerts a strong influence on Saturn's ring system. Mimas creates the Cassini Division between the A and B rings and forces a non-circular shape to the outer edge of Saturn's B ring that is partially locked to Mimas phase.
