黄砂の影響か、透明度が悪い。シーイングも思ったほど良くない状況です。
細かな模様は見えない。もう少しシーイングが改善されればカシニもSEBの縞も
はっきりとするのですが。とにかく、今シーズンは最悪の観測状況です。

>Here are some more multi-spectral Saturn images from the post- opposition period. Seeing has been consistently poor in March, and this night was no exception.
The backscattering effect has faded out by this stage, 10 days after opposition. Compared with my images from Feb 25, the rings have faded a lot in UV, also noticeably in B and IR, relative to the globe. Because the UV change is the greatest, the rings in the (IR)G(UV) image have reddened compared to the earlier results.
