We had a short break in the clouds earlier and I was able to make an observation of Venus.
The theoretical phase was 53%, however in integrated light the phase seemed to be 50%, and in the W#15 filter it was 51%.
Seeing was very poor however so it was hard to be certain!
Illuminated Disk:  There seemed to be two dark patches on the terminator- no streaks or other features were apparent in the poor conditions.
Bright Limb Band: Visible and Complete
Terminator: In the W#15 filter the northern cusp cap seemed to extend beyond the terminator, however seeing was very poor and it is entirely possible that this was a seeing artefact- glare compared with the turbulent viewing conditions.
Cusp Caps: North cusp cap did seem to be larger and brighter.
Cusp Collars: Both present but not easily seen.

Here is the venus report on the 9th june done with the 90mm refractor.
Hard seeing conditions.
Still bright p les, not so here with W29 filter, but brightness from limb with the W29 filter.
Indeed banding pattern there.
