解説(安達)
 7月3日にMare Acidariumの北側にできた白雲のベルトはいったん衰退したが、今日は
再びMare Acidariumの北側に再形成された。しかし7月32日のような明瞭さではない。
Fernando Silva Correa氏は北極上空に新しいダストストームを見つけた。
  The belt of the white cloud which was possible in the north side of Mare
 Acidarium on July 3 declined once, but was formed in the north side of
 Mare Acidarium again today. However, it is not the brightness like 32 
days in July. Mr. Fernando Silva Correa found new dust storm in the
 North Pole sky.

雲に隠れたり、コンピュ−タのトラブルやらで,RGB 画像しか撮れませんでした。
光軸はさらに改善されたようですが,まだ完全ではありません。

Despite supposedly Jetstream conditions,I seem to be getting some reasonably settled seeing conditions. Image attached from this evening,with more dynamic change in the northern cloud structures.


taken early evening and a few hours before my previous submission. As mentioned,seeing is a bit more consistent now and I would say it was average/above average. Nice to see a bit of detail on the screen when capturing. Out of interest,I note in this image that the Indus “bridge” does not show as complete. It also looks like there is quite a bit of light cloud in the southern hemisphere,which is presumably the result of sublimation from the SPC as things start warming up? Image is a bit noisy,but trying not to wash out fine/subtle detail. I would love to understand the meteorology behind the sometimes sharp edges of the cloud structures(eg the linear cloud of 3rd July and also the northern edge of the large northern cloud in this image. Would it be a result of wind?)

Please find attached a recent observation of Mars I made with Dr Hugh Sasse at the University of Leicester's observatory on the 5th July. Conditions were somewhat poor due to the low altitude but not completely hopeless,and I was able to see a number of interesting details. In integrated light:
- Solis Lacus was on the following limb,as was Acidalium.

- Mare Sirenum visible in the far south,with a brightening in the far south- presumably the SPH.
- Various bright streaks and vague dark patches also present on the disk.
- North Polar region very ill defined- a vague brightening.

Filters:
- W#80A (light blue): Interestingly,the albedo features seemed somewhat sharper and easier to see compared to IL.
- W#23A (orange): In this filter the features were somewhat harder to see and more ill defined compared to the views in IL and the W#80A.
