木星 連夜の晴れで透明度が少し上がった。日本では木星の南中の高度が32°と低く、平地の空気の乱れを受け木星が良く見えません。
気流は南中近くで少し安定、木星細部を400倍の倍率でＮＥＢ内部が良く見えた。じっくり見るには双眼装置は良いと思う。
単調な模様にＳＥＢに対しＮＥＢは時に複雑でNEBsには明るい白斑とその後が極めて複雑な模様がある。
各波長での木星画像を見やすくまとめてみました。ベルト位置と描写のちがいが分かります。

Jupiter The clearness of the nights increased the transparency a little. In Japan, the south-central altitude of Jupiter is as low as 32°, and it is difficult to see Jupiter due to the turbulence of the air on the plains.
Seeing was a little stable near the center of the south, and the details of Jupiter were clearly visible inside the NEB at 400 times magnification. I think the binocular device is good for a close look.
The NEB has a monotonous feature, whereas the NEB sometimes has a complicated feature, and the NEBs have a bright white spot and an extremely complicated feature thereafter.
I have summarized the Jupiter images at each wavelength so that they are easy to see. You can see the difference between the belt position and the description.
