Clyde Foster氏のターミネーター付近の白雲は氷晶雲だったようだ。見事に白く記録されている。Eric Sussenbach氏の画像は、
南半球が広く靄に覆われている様子を示している。北の端にある暗い模様を白雲の下に記録できている。Niall MacNeill氏はシルチス
（Syrtis Major:293W,+0〜20）やサバエウス（Sinus Sabaeus;320W〜350W,-10）付近を観測しているが、赤画像を見ると、サバエウス
（Sinus Sabaeus;320W〜350W,-10）の北半分とシルチス（Syrtis Major:293W,+0〜20）の中央付近がよく晴れていることが分かる。
そのため、カラー画像でもこの部分が濃く記録された。SPCの真ん中に砂漠色の白くない部分が鮮明に記録されたのは素晴らしい。
It seems that the white clouds near Mr. Clyde Foster's terminator were ice crystals. It is recorded in white. Mr. Eric Sussenbach's
image shows that the southern hemisphere is widely covered with mist. A dark pattern at the northern edge can be recorded under
the white clouds. Mr. Niall MacNeill is observing around Syrtis Major (293W,+ 0-20) and Sinus Sabaeus (320W-350W,-10).
The red image shows that the northern half of Sabaeus (320W-350W,-10) and the center of Syrtis Major (293W,+ 0-20) are clear.
Therefore,this portion was recorded dark even in a color image. It's great that a clear non-desert white area was clearly recorded
in the middle of the SPC.

Despite what looked like poor conditions on-screen this morning,
I was pleased to get a full set of images out for Mars,Jupiter and Saturn.
On Mars,Solis Lacus is at upper left,and it is nice to see the familiar structure of Valles Marineris coming into view.
Tharsis covers most of the lower right section of the planet.
There is a string of pearls(apologies to my Jupiter colleagues!) effect on the edge of the SPC.
Not much cloud around- just a few isolated spots.

[Niall MacNeill : Wattle Flat,NSW,Australia]
In fair seeing. The South Polar Ice Cap is prominent.
[Mike Hood : Kathleen Georgia,U.S.A.]
A brief spell of good seeing. Mare Cimmerium is central with the 'tuning fork' projections of Sinus Gomer well defined.
