[en] Cassini Ultraviolet Imaging Spectrograph (UVIS) observations of Saturn were obtained on 2009 days 278-280 with the UVIS long slit aligned east-west along the northern auroral oval. Bright quasi-periodic localized bursts of UV emission were often observed with 1 hour spacing that slowly moved sub-corotationally along the main auroral arc. We will report on an apparent correlation of the bursts with the locations of Saturn's moons, and a search for other such examples. We will also compare the UVIS results with simultaneous Cassini Imaging Science Subsystem (ISS) auroral images.
