Some Venus images taken yesterday morning soon after sunrise.
Venus is approaching superior conj. in 2 months' time,phase is 94% and diameter 10.5".
IR image shows only terminator shading and at the poles. Interesting that UV images taken 4 minutes apart appear to show
different markings.
I think this just shows how unreliable webcam filtered images of small planetary disks taken in poor seeing,and then
contrast-stretched,can be,and how careful the observer has to be in reporting what is really representative.
