In the first report,in fair seeing conditions and full daylight conditions,the familiar Venus Y shape is visible. UV filter has been used.
With the second shot,in R light,I used Winjupos and limb darkening feature to detect the Schroeter effect (the discrepancy between measured and calculated phase).
As animation shows,the phase seems to be "right" hence such effect is not clearly visibile.

this is an observation in the visual band and in 900nm in very good conditions.
A strange long streak formation is visible in the northern hemisphere.
I made an animation with Tiziano Olivetti's excellent observation 3h17m before mine.
I made 8 measurements in the cloud moovements from -5S to 30N and calculated an average speed of -72m/s in middle clouds.
