解説（安達）/ Comment by Makoto Adachi
Clyde Foster氏の画像ではMare Cimmerium (W180~W250,-40~0)付近の様子を見事に記録している。SPCからは新しいエッジダスト
ストームが黄色く記録されている。また、Eridania (200~230W,-35~-55)との間に東西に雲のように黄色く幅の広いバンドがあるが、
これはエッジダストストーム由来のダストである。Ausonia (W235~270,-55~-20)にはダストの濃い部分が記録されている。東風に流され、
Hellasよりも西を不明瞭にしている原因の一つだろう。NPフードがはっきり記録された。
報告されてきた画像を見ると、Mare CimmeriumからMare Sirenumの間は、比較的模様がよく見える地域になっているようだ。
宮原氏はSolis Lacus (W90;-28)よりも南側はSPCを取り巻くようにダストが取り巻いている。
In the image of Mr. Clyde Foster,the situation around the Mare Cimmerium (W180~W250,-40~0) is recorded wonderfully.
New edge dust storms are recorded in yellow from SPC. In addition,there is a cloudy yellow and wide band in the east and west
between Eridania (200~230W,-35~-55),which is dust derived from edge dust storm. In Ausonia (W235~270,-55~-20),the dusty part is
recorded. It may be one of the reasons why it is obscured by the east wind and obscure the west of Hellas. The NP hood was clearly recorded.
According to the reported images,it seems that the area between Mare Cimmerium and Mare Sirenum is relatively well visible.
In Mr. Miyahara's image,dust surrounds SPC on the south side of Solis Lacus (W90;-28).

My Mars imaging has been impacted by a number of factors over the last month or so,
but watching and listening to the briefings on the upcoming launch of the latest NASA rover,
"Perseverance",was enough motivation to get me out of bed this morning.
Hellas is just round the corner of the upper right limb. A subdued Elysium is at lower centre.
M Cimmerium sweeps down from upper left towards the arrowhead of Tritonis S,with the two S.Gomer extensions visible at centre.
Not great seeing,but also not terrible either.

The seeing was bad and the transparency was average.
