きく、出ているように思われます。マルガリティファ−(Margaritifer Sinus；
20W,-10）付近にまで及んでいます。残念ながらこの画像以外に報告はなく、
東西方向の広がりがつかめませんでした。(reported by 5 observers)
In Mr. Ikemura's image, the appearance from which the half of the
South Poler Cap was covered with dust was recorded. Everything from
the South Poler Cap to Ausonia (250W,-45) is very remarkable. The
observation in the vicinity of Meridiani (0W,-5) reached from Mr.
Guilherme Grassmann. The influence of dust storm found on May 28
eems to have gone out very greatly. It extends it even to the
vicinity of Margaritifer Sinus (20W,-10). To our regret, the
extension of the direction of east and west was not able to be
gripped because there was no report except this image.

準備中に急速に曇ってしまい、残念でした。
観測に程遠い画像が１つ得られただけでした。

Hello friends,today we hat a Occultation of Mars by the Moon.Unfortunaly was only graze in my location as you can see in my picture.
I made also my first Mars image of this season,and with only 7,9" we can see the Sabaeus Sinus and looks like a kind of cloud or sand storm on this region.
