The venusian equatorial Y is well evident in the ultraviolet image,pretty much invisible in longer infrared wavalenghts. No cloud discontinuity has been detected

I finally had some decent seeing last evening,despite the low altitude (21 degrees) of Venus.
I made IR (889nm,20nm BP),UV and RGB captures.
There was good resolution of detail in the UV image in particular. There appears to be a double chevron shape,with an equatorial bright spot towards the limb.
The IR image also shows good detail and I produced a false colour (IR(G)UV image with it and the UV image.
I also made RGB captures and there was a surprising amount of detail visible in all the colour channels producing distinct banding in the final RGB image.

日没前のシーイングは悪かったのですが時間と共に若干安定しました。
可視光でも日毎に模様が異なるのは判りますが淡くて捉えどころがありません・・・

As always in three different colors and a false color combination.
