解説(安達)
 Christophe Pellier氏の青画像による観測でも、クリセ(Cryse;
33W,+10)付近が明るく記録された。北極方面の雲は非常に
明るく写っている。また、その周囲の暗条もはっきりしている。デュ
ーカリオニスレギオ(Deucarionis Regio;350W,−15)の
東側が明るく見えている。赤や緑で明るく写っているのが気になる。
4月14日の画像に出ていた明るい部分がダストストームだとすると、
ここまで進行したと考えても位置的におかしくないが、情報が少なく
はっきりしない。
 テンペ(Tempe;65W,+45)付近に明るく白斑が出ているが、
これはこの付近に特有の低気圧が出きているものと思われる。Adachi
は、キンメリウム(Mare  Cimmerium;230W,−20)付近を観
測しいるが、目立った変化は見られなかった。

The neighborhood of Chryse  (33W,+10) was recorded even
in the observation by the blue image of Christophe Pellier
cheerfully. The cloud of the Arctic direction is reflected very
cheerfully. And,that surrounding dark  band is clear,too.
It seems that the east of Deucalionis Regio  (350W,−15)
is light. It is anxious that it is reflected by red  image
and green image cheerfully. It isn't strange from the
viewpoint of position even if it thinks that it progressed here
if the light part which could be seen with the image on April 14
is duststorm. But,information doesn't get clear low.  Bright
spot can be seen cheerfully around Tempe  (65W,+45). 
This is thought the low pressure which appears well in this
neighborhood to come for the extension. Adachi didn't see the
neighborhood of Mare  Cimmerium (230W,−20) with the
conspicuous change which but observed it.

We're now facing the northern hemisphere of Mars and its large springtime NPC. Mars will be there for the 2010 january opposition !
Note some thick morning mists over Chryse (see B image)

Here are some Mars images from April 17th. Arygre is filled with haze merging into the SPH. Note the lighter area across Eos/Protei Regio.
