By the picture of Damian Peach, it turns out that there is duststorm which was conspicuous 
to the south of Arabia(320W,+25). Meridiani (0W,-5) is not visible. Although SPC is 
reflected clearly today, it looks a little small. On the other hand, in observation of 
Einaga, the deep portion of Duststorm is recorded near Eridania (210W,-45) from Ausonia 
(258W,-35).　　(reported by 2 observers)

Here are some images from yesterday. This hemisphere of Mars is significantly obscured by dust (see comparison simulation image) though the SPC shines through brilliantly.
Noachis/Hellespontus is still obsucred. Pandorae Fretum,Deucalionis Regio can be seen,while Sinus Sabeaus is partly obscured. Sinus Meridiani is totally obscured by dust and there seems a bright "core" of dust immediatly over its location. There also seems to be some anomalous albedo markings to its immediate north.

シーイングが落ち着くかと思われた頃から雲が出だし、
結局は透明度も悪くなり、良い結果が得られませんでした。
