Abstract
Wide field and planetary camera 2/Hubble Space Telescope (WFPC2/HST) i mages of Saturn's far ultraviolet aurora reveal emissions confined to a narrow band of latitudes near Saturn's north and south poles. The au rorae are most prominent in the morning sector with patterns that appe ar fixed in local time. The geographic distribution and vertical exten t of the auroral emissions seen in these images provide the first new observational insights into the physical mechanisms that power Saturn' s aurora since the Voyager encounters 17 years ago.
