This is my latest image of Saturn. I have finally identified the "new" band as the NNTZ. This is the first time this band was observed here on earth since 1998. Note also that this band is brightening! Note the oval above the NNTZ. Is this a storm or is this Mimas' shadow? This feature also appears on a second image that I made.
As a bonus, Tethys and Enceladus are visible beside Saturn.
