During rev 249, Cassini had one of its closest flybys of Mimas on November 19, 2016 at a distance of about 45,000 km. Images/mosaics were obtained at low phase angles which is great for mapping color variations. Here is a color composite from infrared, green and ultraviolet images obtained at a distance of 85,000 km. The viewing geometry is also shown.
Here filters IR3, GRN and UV3 are displayed as red, green and blue, respectively. The color saturation has been greatly increased to better show color variations. This reveals among other things Mimas' bluish equatorial band (for more on this see e.g. http://photojournal.jpl.nasa.gov/catalog/PIA13426 ). It should be noted that I had to fill a horizontal gap in the UV3 image. The UV3 image originally looked like this: |
