UVIS: Science Highlights
•
Ultraviolet image of Saturn’s rings
This false color image of Saturn’s rings shows
reflected sunlight near 180 nm. The shadow of
the planet on the rings is visible at lower right.
Warmer colors (red) indicate brighter regions
of the rings. (Colwell)

Science Plans (May - Jul 2009)
•
Prepare a short paper on UVIS auroral highlights (Pryor)
•
Apply improved self-gravity wake model to expanded set of occultation data. (Colwell)
•
Study the excess variance in the occultation data to make statements about particle size variations across the rings.
•
Analyze waves in C ring. (Colwell)
•
Determine photon mean path lengths and color ratios of FUV rings spectra taking into account the size of the projected field of view.
