Titan hides Rhea
On 27 October 2009, Cassini caught Titan passing in front of the icy moon Rhea.
The sequence was captured only in clear filters; amateur Gordan Ugarkovic used a different image to colorize Titan. Titan's smoggy haze discolors icy Rhea as the smaller moon passes behind the larger one.
