解説(安達)/ Comment by Makoto Adachi
Damian Peach氏の画像には、SPCから飛び出たエッジダストストームが記録されている。前日の7月2日にClyde Foster氏がSPCの縁に
ダストを含んだ黄色い輝点を記録しているが、ここから北に向かって噴出したらしい。この経度は、しばしばこういった現象がみられる特別な
場所である。また、この画像ではソリス(Solis Lacus;W90;-28)の位置で大きく蛇行するダストストームの帯を記録している。この帯の西の端は、
シレーン(Mare Sirenum;140W〜170W,-30)の中央近くまで進んでいる。また、北のダストストームはリム近くにまで達しているようだ。
Gary Walker氏の画像には、エリシウム(Elysium;215W,+30)の南東側に明るい部分があるが、これは地表のアルベドによるものである。

Mr. Damian Peach's image shows an edge dust storm emerging from the SPC. On July 2,the day before,Mr. Clyde Foster recorded
a yellow bright spot containing dust on the edge of the SPC,but it seems to have ejected northward from here. This longitude is
often a special place where these phenomena occur. The image also records a large meandering dust storm band at the position of
Solis Lacus (W90;-28). The western edge of this belt extends to near the center of Mare Sirenum (140W-170W,-30). Also,the northern
dust storm seems to reach near the limb.
In Mr. Gary Walker's image,there is a bright part to the southeast of Elysium (215W,+30),which is due to the albedo on
the surface of the earth.

My first observation of the planet from home this apparition.
Solis Lacus on view. Note the bright feature on the SPC boundary which looks like a small dust cloud.
Also note the diffuse streak of dust extending south of Thaumasia across Bosporus toward the SPC.
Visually through the eyepiece i also found the contrast of the visible albedo markings quite washed out.

Weather here in the SE USA has made imaging very challenging!
