Jose Luis Pereira氏の画像は、肉眼で条件の良い時に見た火星に近い。この位置では模様は濃くなく、Sinus Sabaeus  (320W〜350W,-10)や
Meridiani (0W,-5)のい写り方を見ると、全面がダスティーであることが分かる。SPCも一部がダストで覆われ、黄色くなっている様子をよく記録
している。Gary Walker氏もほぼ同じ位置を観測しているが、コントラストを強くしたため、模様はよく出ているが、実際よりもはなれたすがたに
なっている。

The image of Mr. Jose Luis Pereira is close to Mars when I saw it under good conditions with the naked eye. The pattern is not
dark at this position. Looking at the images of Sinus Sabaeus (320W-350W,-10) and Meridiani (0W,-5),it can be seen that the entire surface
of Mars is Dusty. The SPC also records a part of it covered with dust and turned yellow. Mr. Gary Walker observes almost the same position,
but the contrast is stronger,so the pattern is better,but it is more lagging than it actually is.
