Unless you’re a night owl, you’re not likely to see the moon and the planet Uranus before your bedtime in late July 2019. They’ll come up in the east more or less together around the midnight hour, and then will climb upward during the early morning dark hours.

The lunar terminator – or shadow line dividing the lunar day from the lunar night – shows you where it’s sunset on the waning moon.
