Phase notes
More than half lit and still filling. Gibbous is an old word for humped, which is what the lit edge does - it bulges out past the straight line of the quarter.
A lopsided moon, bright enough to read a headline by, up for most of the evening.

A phase is only the angle between the sun and the moon as we see it. This one sits at 135 degrees of that angle, three eighths of the way through a cycle that runs 29.53 days.
Crescent means less than half the disc is lit, gibbous means more than half, and the quarters are the two moments in between. The quarter names count orbit, not brightness - a first quarter moon looks like a half.
