Oh,
now I see why I missed it, it almost looks like its "part" of the division between the dark brown belt and the lighter belt below it. Its also a help to know what you are looking for. Must be terrible to have so much detail in your pictures that the moons blend in to the cloud bands.
Thanks for the clarification, I am still very impressed with your images!
Cheers
Chris
