I stepped outside to enjoy the shapes and colors of the clouds:
And then I looked straight up and noticed the moon:
This is a first quarter moon, occurring ~1 week after the new moon. The first quarter moon rises at noon, is overhead at sunset, and sets ~ midnight. It's called a first quarter moon because it's about one quarter of the way through its orbit around the Earth.
And although it's often called a "half moon," only one quarter of the bright side of the moon is visible to us. That is, the dark side directly opposite the bright portion (in this case, on the left) is in shadow. And the other side of the moon (facing away from the Earth) is also half lit and half in shadow.
P.S. Some of the facts above are from earthsky.org.
