Software binning.
Enhanced with unsharp masking method.

Caption:
Please note that the darkness of SEBn and SEBs,
which is darker in shorter wavelength,
it means they are red.
And SEBZ is the most distinguishabe from SEBn and SEBs in Orange images.

説明：
SEBnとSEBsの濃度に注意を払うべきである。それらは、短波長になるほど暗い。
つまり、それらは赤い。
そして、SEBZの、SEBnとSEBsからの識別はオレンジ色で撮った画像において、最も明確になる。

１２月７日の土星観測レポートをお送りします。
南極の小ゾーンはまだ、見えていますが、特に、変化はないようです。
