Here is a report performed with the VMC110mm under good images on best moments and operated under a transparent sky.
A banding pattern was collected with some difficulty,
boths cap not conspiscious clear,caps being probably faded by the planet tilt axis and more by planet phase,no bright spot.
AL was more than suspected with the YG,R,B and no filters with 69/100x magnifications,planet heigth 67°,
also with a faint light yellowish blue tint well noted near the terminator; the extension was not full dark side,
except for the B and R segments. Cusp extension was there as shown,
rather faintly. No time for inserting stronger magnifications. Some dark markings on the AL light was there (as drawn carefully).
The light intensity on dark side was degrading from terminator towards the dark side limb,
but not full extension,quoted almost L1- (3 the highest).
AL light intensity is not growing since days,reaching L1 level on the 23rd april,the maximum observed.

Some dark patches are visible. Average seeing conditions.

Attached is a series of drawings of Venus made yesterday evening.
Initially seeing was poor but soon improved to around AIII with moments of reasonable definition.
The cusp terminator anomaly seems to remain whereby the terminator at the cusps makes a much shallower angle than it should from the true phase angle.
The effect is present in a number of images and drawings I have received as Section Director. Yesterday I found the phenomenon to be much more obvious in the W21 orange filter.
Bright Limb Band: Visible and complete
Terminator: Geometrically regular
Cusp Caps: Not seen.
Cusp Collars: Not seen.
