First Quarter

The Moon is now a quarter of the way through its monthly journey and

you see half of its illuminated side. People may casually call this a half

moon, but remember, that’s not really what you’re witnessing in the

sky. You’re seeing just a slice of the entire Moon ― half of the

illuminated half. A first quarter moon rises around noon and sets

around midnight. It’s high in the sky in the evening and makes for
excellent viewing.

Waxing Gibbous

Now most of the Moon’s dayside has come into view, and the Moon

appears brighter in the sky.
