The theoretical phase of the planet was 50.1%,however dichotomy has yet to occur in integrated light or with the W#15 filter.
Other points include:
Illuminated Disk: Three shadings seemed to be present on the disk,although the one ion the centre was by far the most prominent.
There also appeared to be a brighter spot on/near the limb not far from the south cusp cap.
Seeing was rather poor so it could have been some sort of seeing artefact although it was present in both IL and in the W#15.
Bright Limb Band: Visible and complete. Terminator: Geometrically regular.
Cusp Caps: In IL,both seemed about equal,however in the W#15 the southern cusp seemed to be larger and brighter.
Cusp Collars: Again in IL both appeared to be about the same,but in the W#15,the southern collar was more prominent.
