Hi all,
Here are some Saturn images from Dec 7th. Of note is
that Gu Yu's spot at L2=290 has disappeared,
having probably been fading when it was first
detected. No other new spots are noted.
Also attached is a brightness plot of an image from
Oct 22nd, with light sharpening applied, showing the
brightness variations across the ring system.
Best Wishes
Damian
