When the moon is positioned “next to” the Earth, you can see half of the portion ofthe moon that is lit up. In other words, you can see a quarter of the moon. It looks like a right-sided half circle in the sky. We call this phase _________________. This is the 2nd principal phase.

• New Moon

• First Quarter

• Third Quarter

• Full Moon
