July's last quarter moon will set by midday on Sunday (July 9), so plan accordingly to see it late tonight.
The moon will be in its half-lit third-quarter phase when it rises from the eastern horizon shortly after midnight overnight tonight before setting to the west around 1 p.m. ET (1700 GMT) on Sunday (July 9), according to In-The-Sky.org. During this phase, which gets its name from the fact that it falls three-quarters of the way through the moon's 29.5-day lunar cycle, the moon will be illuminated on its western, sunward side.
