The Venus report of 5th May done with the 90mm refractor is transmitted for your perusal.
I am doing a 4 days period observation each time in order to try to see some variations all along weeks.
4 days is almost the atmospheric speed rotation at the equator area.
We will see, just a method of investigation.
At present, no specific comment to raise apart it was a difficult observation.
