The disk size is now notably smaller,so higher powers have to be used to see anything at all.
The theoretical phase was 55.2%,but visually in IL the phase appeared only to be about 51%-
of course it is difficult to be sure in such poor conditions. Other points include:
Illuminated Disk: A couple of vague streaks visible- they were easier and better defined in the W15 filter.
Bright Limb Band: Visible and complete.
Terminator: Geometrically regular.
Cusp Caps: Southern cusp cap seemed to be marginally brighter than then northern cusp.
Cusp Collars;  Both seen but not easily.
