Description

FranckIM06 asked me about the delineation between the EZ and NEB and the fact there is a strange discontinuity there. I had made this animation previously so I knew it was a real feature rotating with the planet. I have given these images an extra sharpen to help bring out the very subtle features in the planet's atmosphere. I chose the Red channel because the definition is better here. The bulk movement in the North Polar Region (NPR) is quite clear and the animation makes it much easier to see the multiple features there versus a single image.
I was about to crop and remove the rings, but I thought I should look at them before I did to see if I could detect any movement.......and I did. Now it may be my eyes and they may be artefacts, but it seems to me that there is very distinct circular motion of radial features in the A and B Rings and more noticeable in the former. The motion is in the same direction as the planet's rotation. I see this motion on both sides but more distinctly on the right.
Is it my imagination?
