The 1st quarter moon comes on September 6 at 03:10 UTC. You’ll find the moon high up at sunset on both September 5 and 6. It appears nearly or completely half-illuminated, like half a pie.

Unless they pass directly in front of the sun, causing a solar eclipse, new moons generally can’t be seen. They cross the sky with the sun during the day. The next new moon happens on August 30 at 10:37 UTC.

A last quarter moon rises around midnight and sets around noon the following day. This last quarter moon falls on July 25, 2019, at 01:18 UTC; that translates to 9:18 p.m. EDT on July 24.

Full moon – when the moon is most opposite the sun for this month – falls on July 16, 2019, at 21:38 UTC. This full moon will undergo a partial lunar eclipse.

A waning crescent moon is up in the east before sunrise. It’s waning toward new moon, when the moon will be between the Earth and sun.

A waning gibbous moon is a moon between full and last quarter. Watch for this moon phase from late night through early morning.

Many people report seeing earthshine on a waxing crescent moon. That’s when the darkened portion of the crescent glows dimly with light reflected from Earth.

A waxing gibbous moon appears more than half lighted, but less than full. It rises before sundown and sets somewhere between midnight and dawn.

Half the moon always faces us. And half the moon is always lit by the sun. But, in the language of astronomers, there are no ‘half moons.’
