Two drawings I made of Venus on Sunday 4th June.  A nice example of the Schroter effect- the thick Cytherean atmosphere scatters the sunlight, as a result the observed phase of Venus is always these than the theoretical one.  The theoretical phase was 50.1%, but in IL it was 45% and in the W#15 it was 48%.
