2009年9月23日
どの観測者も、北極雲を全周で広く捉えている。柚木氏のBBが画像によれば、
低緯度地方に淡い氷晶雲の出ている様子が確認できる。また、南極にも雲の広がっ
ている様子が記録されている。
南極の雲はBの画像よりも淡く見えるが、画像処理による違いの可能性が高い。お
そらく、同じレベルだろうと思われる。Jean Jacques Poupeau氏の画像に見られ
る、limbの明るいスポットは、朝霧によるものだろう。
(reported by 3 observers)
Every observer has caught North Pole clouds widely by all the circumferences.
According to the image in BB of Mr.Yunoki, signs that light water ice
cloud has appeared to low latitudes can be checked. Moreover, the figure
in which clouds have spread is recorded also on the South Pole. Although
south poler clouds look lighter than the image of B, a possibility of
being an image-processing difference is high. Probably, it seems that it
will be the same level. Bright spot of morning limb looked at by the
image of Jean Jacques Poupeau will be based on morning mist.

Notes:
North polar hood indeed very well present but
the morning side brighter than the evening
side (the line separation is not a rift!).
See the border line hood very contrasted
(the darkest points).
Hellas bassin clear! Nor really because at
2H35UT impossible to see,therefore a bright
patch extending on Mare Thyrenum (without
filter W.F. whitish,W8 clear but not whitish,
W80A clear not whitish,V light seems to be
Visible clear but no enough time to confirm
Because haze incoming at time obs.
A clear-bright patch on Lybia area (W.F.,W8
Covering the south of Syrtis Major,nothing in
Blue light.
Electris is well seen under W.F. and not with
coloured filters. Eridania was not seen clear
or bright!
Amazonis/ Memnonia seems under haze in B
light at the terminator.
General comment:
A good to excellent observation under still
images,observations stopped by ground haze
here for getting a clear view status in V light.
W.F.: means without filter.
Regret to donot assess with the G filter.
