Very good seeing conditions. I made a comparison RGB image (RIR enhanced). Here is a mini report:
There is bay in the P side of the methane bright (MB) South Polar Cap.The Red S.P.R. Spot is MB.
S.S.Temp.Region AWOs are MB as normal.The cyclonic white oval (CWO) between Between A3 and A4 is still MB.Oval BA is rising and is MB as usual.
In the S.Tr.Z the F part south of SEB is methane brighter then P part which is closer to GRS.
SEB is generally methane dark (MD) with some methane darker spots on the southern part.The turbulent region on the P side has some MB areas.
In the Equatorial Region there are MD projections and at least one MB area near CM.
NEB is MD and N.Tr.Z. smoothly MB. At NNTBs there is a litle red spot which is MB at CM2 309,B" +34. There is a white MB spot at CM2 291,B" +41
In the NPR there are many little white spots which are also MB.
The North polar cap is thin and extends south,a diffrent aspect in relation to SPC.

After discussing with my friend Almir Germano difficulty of creating a GIF
that all outlets would keep the same tone light and dark I decided to be more careful with this .
First before starting the shots for the establishment GIF capture parameters that best matched the conditions of seeing tonight.
I did several pilots processed , analyzed and selected in a given parameter to FireCapture that the photos stay with the same contrast .
From one film to the other a 10-minute interval was established and were collected around 3000 frames in each of which was exactly 1070 frames stacked .
All parameters used in AS ! 2 were the same for all films and the same thing was done to process each obtained from AS ! 2 TIFF image using Registax , Photofiltre and Irfan .
