解説(安達)
 昨日のネクター(Nectar;70W,-23)を中心としたダストストームは変化を続けている。ネクター(Nectar;70W;-23)付近は相変わらず明るいままだが、その南北の地域は晴れてきた。そのためネクター(Nectar;70W;-23)付近だけが際立って明るく見えるようになった。
 デルフィーニ(Delphini Portus;70W,-35)のダストストームは西に移動し、デルフィーニ(Delphini Portus;70W,-35)は本来の暗さを取り戻した。その代わり、そのすぐ西にあるタウマシア(Thaumasia;80W;-38)が明るく見え、ここにダストストームが移動したことがわかる。ダエダリア(Daedaria;120W,-30)付近のダストストームは前日よりも明るく変化し、少し発達していることがうかがわれる。一方、アルギレ(Argyre;35W,-50)南西のカンピ(Campi Phlegraei;60W,-56)にあったダストベールが発達してきている。
 前日に引き続き、アスクラエウス(Ascraeus;105W,+20)付近が、大きな暗斑として目立っている。
 南極冠は黄色っぽく、さらに白っぽく、複雑な姿をしている。(reported by 1 observer)

Dust storm which has a center in Nectar (70W,-23) is continuing change yesterday. It is still bright in near Nectar as usual. However, the south and north area came openly. Therefore, near Nectar is conspicuous and it came to look brightly. dust storm of Delphini Portus (70W,-35) moved west and Delphini Portus regained original darkness. Instead west Thaumasia (80W,-38) looks bright immediately. It turns out that dust storm moved here. Dust storm near Daedaria (120W,-30) changed more brightly than the previous day, and is developed for a while. On the other hand, dust veil which suited Campi Phlegraei (60W,-56) of Argyre (35W,-50) southwest has progressed. Near Ascraeus (105W,+20) is conspicuous as big dark section following the previous day. Yellowishly, SPC is whitish and is carrying out the complicated figure. (reported by 1 observer)

Here are some images from this morning. Good seeing. The whole aspect of Mars at this longitude has become unrecognisable. The changes from yesterday are notable with significant movement of dust, includng a bright core of dust over nectar/protei regio. Dust remians over Solis lacus, and i also suspect dust across the southern polar areas.
