I do like poetry, but if we are looking at a crescent moon, in our night, it means that the bulk of farside is facing toward the sun, and will therefore be brighter than nearside
The far side is darker during lunar night (lit by starshine only; Full Moon on Earth) than the near side during lunar night (New Moon on Earth), because it receives both star- and max. Earthshine.
I'm not sure about Crescent Moon though: that only narrows the brightness gap slightly, right? Or I’ll have to ask if there’s an astronomer on board our flight.
