　Clide Foster氏の画像ではHellasの白雲が非常に明るく記録され、とりわけ、西の端に明るい部分を記録している。これは今年の
特徴だろう。この様子はStanislas Maksymowicz氏の眼視観測でもとらえられている。また、Syrtis MajorやLibya付近には顕著な
氷晶雲があり、低緯度地方を東西に覆っている様子がはっきりと記録された。
　In Mr. Clide Foster's image Hellas' white clouds are recorded very brightly, especially the bright clouds at the western edge. 
This is characteristic of this year. This situation is also captured by Mr. Stanislas Maksymowicz 's visual observation. In addition, 
there were remarkablewater ice clouds near Syrtis Major and Libya, and it was clearly recorded that the low latitude region covered 
east and west.

I was privileged to spend another Xmas with my 92 year old dad and my sisters family down near Durban.
On a further personal note,I am pleased to share with my Planetary friends that
I proposed to Marina before Xmas and we will be married in March- nicely timed so as not to interfere too much with the Jupiter,
Saturn and Mars oppositions a few months later!!
We returned home on Tuesday to cloudy weather,but I woke early this morning to clear skies and a nice late Xmas present- some nice seeing conditions!
The attached image set shows Syrtis Major to the centre left with possible cloud hanging over it(most noticeable in the G image)
Below Syrtis Major,a number of familiar features are detected including Boreosyrtis and a few albedo features south of Protonilus. The NPC is clearly seen.
Hellas seems to be filled with cloud,although there appears to be a dark indentation/feature towards the southern limb.
It would be nice if these seeing conditions stayed for a while……

I tried this morning also with the 150mm cassegrain and 316x this time.
Weather a little cold at last, frozen ground, a little, made a rather stable atmosphere. Quoted 6 to 7 sometimes /10.
So at last something in a way consistent.Please have a look on the furnished sketch.
Brightenings given with arrows for location.North cap not seen, just only suspected. 
As on the 26th observation the dark collar ring is not the collar surrounding the cap itself.
Hellas seemed to be away of its location by the brightening captured. Nothing to say more with the means engaged.
