Please find attached an observation I made of Venus yesterday in good seeing conditions.  There was a number of subtle cloud markings on the disk,and interestingly the markings and bright cusp caps came out best in the W47 violet filter.
We are now very close to dichotomy- in the drawing the phase looks like it is at 50% but it is in fact 51%.  In poorer seeing conditions I imagine it would be incredibly difficult to distinguish that!  I have been comparing the phase to a number of printed blanks that I have and I find that really helps in determining if the planet is at 50% illumination.  Also:
Bright Limb Band: Visible and complete but near the centre of the disk whereby the bright limb seems to extend onto the disk into a bright region.
Terminator: Geometrically regular- terminator shading quite dark,and this is the first time I have been able to see it proeprly in this elongfation.
Cusp Caps:  Both about equal- northern cusp cap seems to be a bit brighter.  Both seemed very large in the W47 filter.
Cusp Collars:  Both seen- probably about equal.

Conditions were even better than the day before,so B and UV shadings came out quite prominent. But note also the faint bands in the nothern hemisp. visible in G and IR.

A compilation of my observations of Venus from May 26th through at least seven different filters. Interestingly even normal RGB showed details (G and B taken with IR rejection filter). Best show of all came from IR 807.
