Seeing was better than the second part of the evening: fair to good so 5-8/10.
The transparence was terrible: about 4/10 worse than about 3hours after.

Hi everyone, with much delay here are my (maybe) last Saturn images of the
season. They are all of average quality at best and conditions were fair.
Just two remarks :
1) Note the IR1000 image of march 8th. The 1-micron filter was used with the
same method as for the UV filter : the ATK-1HS used in long-exposure mode
along with the C14 and a short focal lenght. Each frame was exposed 2
seconds and one thousand has been stacked (it has been long to grab them all
;o) ). Saturn's globe is quite dark at this wavelenght, and I was just
wondering if the image was a bit affected by methane absorption, as for my
Jupiter image of march 6th. Cassini took an image at 720 nm on february 16th
and the belts/zones pattern looks similar to me
(http://photojournal.jpl.nasa.gov/catalog/PIA05381).
2) Some changes in the globe have been taken place in near-IR, in march.
With the IR700 filter two belts have appeared, the first one around -45° and
the second near the SPR. From december to february those two belts were not
present in the images. With the IR780 filter, the SEB looked suddenly thick
in march, while it was totally not present in the previous monthes.
Best wishes

この当時、未だ会員では無く、鑑賞写真気分でしたが、ずっと気になっていた白斑の確認の為、最近また皆さんの写真を再見し、報告を思い立ちました。
この二箇所には 白斑らしき物が写っているように思えます。
今更ながらの古い報告ですが…
