Finally,better seeing conditions in the morning hours of Venus visibility high in the sky.
A dark linear feature that I interpreted as the cloud discontinuity (CD; arrowed in enhanced insets) is visible in all IR filters used (IR685,Sloan z'-s' and Sloan Y') but not in UV (where polar regions and an equatorial band are brighter).
All visible features rotate with the atmosphere,as seen in the gif animation between first and last images for each filter (from left to right,IR685,z'-s',Y' and UV).
Let's wait and see if in a 4-day period the linear feature returns.
