Arsia Silva Mons (W120,-3)の雲は、今日も記録はなかった。火星の地形の起伏の激しい地域がターミネーター近くにくると、影が見えて、
興味深い姿を見せている。井上氏の画像ではArgyre (30W,-50 ）の通常の形が記録された。この付近のダストが淡くなってきたことを示して
いるように見える。ただ、肉眼で確認できるほどではなかった。そのほかには目立った様子は記録されなかった。
The cloud of Arsia Silva Mons (W120,-3) was not recorded today. When the rugged area of Mars' terrain comes close to the terminator,
a shadow is visible,showing an interesting appearance. In the Inoue image,the usual shape of the Argyre (30W,-50) was recorded.
It seems that the dust around this area has become lighter. However,it was not visible to the naked eye. No other prominent appearances
were recorded.

１５時頃と１６時半頃の２セット撮影しましたが、１セット目は薄雲を通しての撮影でシーイングも酷いものでした。２セット目は晴れ、シーイングも多少は改善されました。

夕方の豪雨のあとなかなか晴れませんでしたが、小さな晴れ間で辛うじて撮影することができました。

このところ、アルシア・モンスに雲がかかる。他のタルシス痴呆の山には見られない。南極冠は溶融が進んでいる。

Here is a mars report performed with the 127mm apo refractor EDT under a transparent and relatively stable atmosphere.
Features with the violet filter was still there but contrasty lowered.

Good day! Mars watched tonight,the picture was completely different! Seeing was great.
I noticed the first changes on the terminator at 22:13 - a bright elongated spot became distinguishable,
tapering towards the terminator and bending to the south,it formed a gentle light ledge,similar to an ancient barrow.
Over time,this protrusion increased,on the northern side,at first,
a dark dip into the disk of Mars in the form of a half drop formed.
Then it became sharper and longer,in the form of a half triangle.
At about 22.32 this dark ledge visually merged with Terra Sirenum,
due to which Terra Sirenium became visually larger and sank to the north.
The light spot changed its shape,as did the dark ledge on the disk from the side of the terminator.
Sketched the dynamics of these changes from memory and recordings from a dictaphone. At 22:50,
this phenomenon completely disappeared,as if it had never happened.
At low magnifications (99-170x) I noticed the extremely pleasant color of Terra Sirenum -
it was similar to the color of Jupiter's scallops,only with a dark turquoise green tint!
This is the first time I've seen this. Above,I do not know the name,the long continental formations were brown.
Nazar scoop are marked with number 2.

夜半になって、雲が若干薄くなった。火星は赤いので、木星よりも観測しやすい。今日はArgyreとNoachisあたりがやや明るかった。
Argyreは形が見えない。ダストのせいだと思われる。火星像全体が低コントラストで、模様が非常に見えにくい。

fairly good seeing and good transparency. The attached is a Winjupos 6 minute image (2 x 4,000 frames).
[Kev Wildgoose:Oswestry,UK]
These are taken with 2 minute R and IR videos,and 1 minute G and B videos.
Seeing has actually been pretty poor,with something of a northerly airflow of late.
