I had slightly better conditions last night.
Blue still does not look to be quite back to normal to me.

I made an observation of Saturn on February 15,2007 at 03:00 U.T.  using my 9-inch F/13.5 Maksutov-Cassegrain.
The amount of detail  noted over the globe and rings was impressive,as noted.
The South  Equatorial Belt (SEB) displayed complex detail (dark condensations  and bright streaks).
I welcome any comments that you may have on my  observation.

コメント：風が吹いていたが、次第に弱まって撮像の後半は比較的シーイングが良く
     なった。白斑などがあるようですが、はっきりしません。
     南極付近はオレンジ色が少し強く思えます。
