Harvest moon

If you're located in the Northern Hemisphere, you might have the opportunity to spot a special full moon in the sky this weekend: the Harvest Moon This month's special full moon gets its name because its appearance low in the southeastern sky for several nights historically afforded farmers extra time for harvesting crops. Before the invention of electricity, farmers relied on bright moonlight in the late summer to gather their ripening crops after sunset.

The moon typically rises about 50 minutes later each night, but during several nights around the Harvest Full Moon, it can rise between 25 to 30 minutes later across the United States. In other Northern Hemisphere locations, like Canada and Europe, the moon can rise just 10 to 20 minutes later around a Harvest Moon, according to SPACE.com's skywatching columnist Joe Rao.
