解説(安達)/ Comment by Makoto Adachi
1)地上観測を基にした解説(Comments based on images shot on the earth)
  Mark Lonsdale氏の画像を見て驚いた。一斉に赤道を越え、南半球に進行しているからだ。全球に広がる様相を呈してきた。Gregory
H. Revera氏の画像では、Sinus Margaritifer付近に明るい部分を記録している。この部分を中心に、広がっていくものと思われる。
  I was surprised to see Mark Lonsdale's image. It crosses the equator all at once,and it progresses to the southern hemisphere.
It has been spreading across the globe. In the image of Gregory H. Revera,the bright part is recorded near Sinus Margaritifer. It seems that
it will spread around this part.

2)MRO画像を基にした解説(Comment based on the image from MRO)
 この日の地上からの観測は、良い条件での観測がなく、MROとの比較がしにくい。Eden北方のダストストームは弱く東風によって
西へ流されている。一方、Xanthe付近は西風になって、ChryseとXantheとの中間でぶつかっている。そのためこの両方からの風のぶ
つかる所でダストストームは濃くなり、雲頂も高く写っている。Marineris東部の谷の中はダストストームによって黄色く観測されている。
 大きな動きとして、Sinus Margaritiferを覆い始めたダストストームは、翌日に大きく広がることになる。
  Observation from the ground on this day has no observation under good conditions and it is difficult to compare with MRO. The 
dust storm north of Eden is weakly drained to the west by easterly wind. On the other hand, the vicinity of Xanthe becomes westerly 
wind and hits between Chryse and Xanthe. As a result, the dust storm becomes thicker and the cloud top is also high in the place 
where the winds from both of them collide. The inside of the valley of the eastern Marineris is observed to be yellow by the 
dust storm. As a big move, the dust storm which began to cover Sinus Margaritifer will spread widely the following day.

My latest Mars image,taken in quite poor seeing conditions.
I have included the WinJUPOS image so that it is possible to estimate where the dust storm has reached.
