The planet is was just 8.3° west of the sun and 2h 43m past inferior conjunction,I had hoped to observe the whole of the conjunction the skies didn't properly clear until after the event.
The enormous disk size of 59.4" meant that the planet was very large even at x67. Seeing conditions were terrible but I suspect some cusp cap extensions around (or less than) 10°.

Today the big day of the conjunction. . In the early morning the atmosphere
was quiet,but there were many clouds. In the beginning of the afternoon the
clouds disappeared,but the seeing went down..
Here a colour image made with the ASI224 colour camera. The IR image was
made with the ASI290 MM camera and a 850nm filter.
This compilation of Venus images from March 2017 illustrates that on its way
to the conjunction date 25 March 2017 the orientation of the thin Venus
crescent is slowly changing.

After 2 days of trying to find Venus between a layer of cirrus I fortunately managed to find Venus on the day of inferior conjunction.
The disk of Venus was only illuminated for 0,01% creating a beautiful razor thin crescent
