Javier Beltran Jovani氏の画像を見て驚いた、タウマシア(Thaumasia Foelix;70W〜105W,-30〜-43)が明るく写っている。
コントラストを強くした副産物のようだ。Antonio Lasala氏の画像ではいつもと同じ暗さで、安心した。コントラストの調整は注意が必要だ。
二人の観測者ともにオーロラ(Aurorae Sinus;53W,-10)の東半分を暗く記録しており、元に戻りつつある様子が分かる。
前日の7月7日に、アルギレ南方のSPCの縁が黄色くなり、ダスティーになっていたが、今日ははっきりしたダストが北に向かって
噴き出しているのが記録されている。予想通りになったようだ。
Surprised by the image of Mr. Javier Beltran Jovani, Thaumasia Foelix (70W ~ 105W, -30 ~ -43) is bright. It seems to be
a by-product with strong contrast. The image of Mr. Antonio Lasala was as dark as usual, so I was relieved. Be careful when
adjusting the contrast. Both observers are darkening the eastern half of the Aurorae Sinus (53W, -10), showing that it is recovering.
On July 7, the day before, the SPC south of Argyre (30W,-50 ) had turned yellow and became dusty, but today it is recorded that
clear dust is erupting north. It seems as expected.

This is a classical view of Mars with Syrtis Major to the north and the Hellas Basin to the south and both close to the Central Meridian.
The usual shape and yellow colour of the Hellas Basin is obscured by what appears to be dust clouds.
These are also apparent to the south of Sinus Sabaeus and clearly extend around towards the Vallis Marineris as observed in recent images of that region.
Although this activity doesn't have the intensity of 2018, which culminated in the global dust storm of that apparition,
the fact that this is the dust storm season on Mars is manifest.
