Here is a report performed with the R76mm under good images on best〓moments and operated under a very transparent sky.
A sign of cloud pattern was not collected,boths cap〓not conspiscious〓clear,〓caps being faded by the planet tilt axis and more by planet phase,no bright spot.
AL was more than suspected with the YG,R,almost full dark side,as shown,with R and with polar filter exhibiting almost the full dark side,〓 with 60x/88x magnifications,planet heigth〓47°,also with〓 a faint marked light brownish tint well noted near the terminator and away. Cusp extension was evaluated to〓be none.
Dark markings on the AL light was there at the issue of the session (not drawn).
The light intensity on dark side was degrading from〓terminator〓towards the dark side limb,partial extension with the YG,R filters,〓 using polar filter,R and no filters on almost full dark side extention,the intensity was not reaching a L1 〓(3 the highest) .
Turning the polar filter by 90° extincted〓the light level to a reduced level,but not null,the variation of light remained〓subtil but well noted,its extention〓limited to the dot line on the dark side.〓
At the best angle for the max transmission,extention〓was almost full dark side with the dark markings difficult to locate acurately.〓
Using the 60/88xx magnificationx the AL light tinted also almost fully the dark side to〓a brownish color from 16H35UT and after,not before,〓turning it by 90° the light extention〓was reduced to the terminator area.
The main event was the coloration change of the AL,now brownish,in spite of a reduced light intensity and extention〓comparing with past days.
