A cool morning (11C) and relatively good seeing for Venus. For once,the clouds and aircraft contrails co-operated.
The UV markings,unusually,were visible on-screen.
Also,I believed I could see them visually. This is the first time this has happened.
Also,and which fits in with the above,for the first time I think I have recorded real details in the IR. These are different to the UV markings,and also not the inverse of them. It seems that on this occasion there was contrast present in the Venusian atmosphere right across the light spectrum.
Interesting how the shape of the planet is different between UV and IR. In UV,the N polar region (bottom) seems distended at the terminator.
