Tonight – August 22, 2015 – you’ll find the moon, the star Antares and the planet Saturn. Our chart at top shows them as they appear on the evening of August 22 from North America. No matter where you live worldwide, look for the moon as evening falls. You’ll see it at or near first quarter phase, and near this star and planet. A first quarter moon appears half-illuminated in our sky.
The first quarter moon falls on August 22 at 19:31 Universal Time. Although the first quarter moon happens at the same instant worldwide, the clock reads differently by time zone. At the U.S. time zones, the first quarter moon occurs on August 22, at 3:31 p.m. EDT, 2:31 p.m. CDT, 1:31 p.m. MST or 12:31 p.m. PDT.
From Earth, the first quarter moon appears half-lit: 50% illuminated by sunshine and 50% covered over in the moon’s own shadow. The terminator – shadow line dividing the lunar day from lunar night – shows you where it’s sunrise on the waxing moon. Scan along the terminator with binoculars or the telescope for your best three-dimensional views of the lunar terrain.
If you were on the first quarter moon, looking back at our planet Earth, you’d see a half-lit last quarter Earth. The terminator – the shadow line dividing day and night – would show you where it’s sunset on waning last quarter Earth.

Bottom line: No matter where you live worldwide, look for the moon as evening falls on August 22, 2015. It’ll appear half-illuminated, shining near the star Antares and the planet Saturn. Watch the moon in the evenings ahead, as the moon moves past Saturn and toward Antares.
