解説（安達）
メリディアニ(Meridiani;oW,-5)とマリガリティファー（Sinus Margaritifer；２０Ｗ，−１０） の間に明るいregianal duststormが見られる。前回のシーズンに発生し、HSTで記録されたものと同じ姿をしている。デューカリオニスレギオ（Deucarionis regio；３５０Ｗ，−１５）の東部からヘラス（Hellas；２９５Ｗ，−５０）にかけて、淡いバンドが出来上がっており、何らかの変化の合ったことがうかがえる。ノアキス（Noachis；３５０Ｗ，−４０）は晴れているが、アウストラレ（Mare Australe；３１０Ｗ，−６５）付近はダストに覆われている。南極冠は写っているが、明るさが低く、淡いダストに覆われているらしい。(reported by 1 observer)
Bright regianal duststorm is seen between Meridiani and Sinus Margaritifer (20W,-10). It generates in a last season and the same figure as what was recorded by HST is carried out. It applied to Hellas (295W,-50) from the eastern part of Deucarionis regio (350W,-40), and the light band is done. It turns out that a certain change was here. Although Noachis (350W,-40) has cleared up, near Mare Australe (310W,-65) is covered with dust storm. Although SPC is reflected, brightness is low and, seemingly, is covered with light dust veil.

An image of dusty Mars from July 5th UT.
Conditions were rather poor but at least the sky stay cleared which
was a minor miracle. Seeing was affected by the jet stream among
other factors.
Argyre looks bright. Sinus Sabaeus & Sinus Merdiania look like they
are clearing up along with Hellas and Syrtis Major which have
largely cleared up already.
Bright patch seen near Margaritifer S.
SPC was visually observed and appeared white but dull.
Hopefully the conditions will improve here soon, as it is
frustrating imaging the storm in poor conditions, similar to the
2005 event.
