Hellas (275~315W,-30~60)のダストが次第に薄れてきたが、中の模様がそれに伴って見えてきた。肉眼でもいつものシーズンより暗く
なっているようすがよくわかる。この付近は、最近になって淡く白雲が見えるようになり、太田の画像を見ると、かすかに白くなっ
ている様子が分かる。
Peter Edwarsの画像は、SPCの周辺に白雲を記録している。Constantin Sprianuは、リムから広がる朝霧を記録している。肉眼で
見ると広い範囲が白っぽくなって見えるが、この画像の青っぽい地域がそれにあたる。Stanislas Maksymowiczもその様子を肉眼で
とらえている。
The dust of Hellas (275 ~ 315W,-30 ~ 60) gradually faded,but the pattern inside became visible along with it. This pattern is
clearly visible to the naked eye as it is darker than usual. In this area,white clouds have recently become visible,and Ota's image
shows that it is slightly white.
The image of Peter Edwars records a white cloud around the SPC. Constantin Sprianu records the morning mist spreading f
rom the limb. The large area looks whitish to the naked eye,but the bluish area in this image corresponds to it. Stanislas Maksymowicz
also sees it with the naked eye.

雲がうすくなるところを見計らって断続的に撮影。それらを寄せ集めて、ようやく１セットにしました。
シーイングも酷いものでしたが、記録として報告します。

Seeing was jittery but reasonable detail visible in the Oxia Palus to Aurorae Sinus region.
Sinus Miridiani on the left. No clouds visible.

In spite of the average to poor images,here is a report of mars performed last 17th with the 150mm refractor.
Comparing with the 16th report,veils on Hellas at terminator,Aeria at terminator,
Sina -Solis Lacus seemed to extent in surface.
Brighter on the yellow channel but also clear on the green channel: rather misty,
except at the limb and at the terminator the veil signatures are rather dusty.
Still white hazze on the north pole area,the violet layer still transparent.

Passing cloud present at times but the seeing was fairly good at around AIII.
The disk size is now rather large and at x300,there is a lot of fine detail:
- SPC easy to see at these longitudes- this is the first time I have been able to see land behind the cap!
Argyle I and II seen although these regions were not particularly bright.
Mare Erythraeum contained a lot of fine detail,Margaritifer Sinus quite dark and the extension of Niliacus Lacus seen nearby.
Solis LAcus on the following limb,Auroae Sinus nicely defined,bright clouds again in Ophir.
Thymiamata,Deucalionis Regio and parts of Chryse brighter- cloud activity?
Niliacus LAcus and Nilokeras seen. Acidamilum covered by a strong bluish-white haze,no doubt the NPH.
[Paul G. Abel:Leicester:United Kingdom]
It's growing bigger and bigger (and very cloudy in this view).
[Constantin Sprianu,Otopeni,Romania]
