---

some moments of good seeing allowed multiple imaging yesterday,using two IR filters and an UV filter.
Mid altitude cloud features were similar with Sloan z'-s' and 1000nm/20nm (which may be useful,in the future,to explore the night side) but with more contrast with the Sloan.
A "hook-like" IR feature is seen (arrowed in a more enhanced image).
This,and all other IR albedo features rotate with time (see IR gif from first and last Sloan IR image),UV bright features were also seen and rotate with time (see gif from first and last UV image).
Three of the UV images were further enhanced to better show bright features. Some exaggerated limb brightening apparently occurred.
