The full moon in October is also known as the “hunter’s moon” because it marks the beginning of the hunting season, signaling to hunters to begin preparing for colder conditions, according to the Old Farmer’s Almanac. The “hunter’s moon” follows the “harvest moon,” a moon phase that signals the best time for harvesters to reap their crops.

October's supermoon, known as the "Hunter's Moon," will be the biggest and brightest full moon of the year. Why it matters: The third of this year's four consecutive supermoons arrives during an active month of skywatching between rare northern lights sightings and the once-in-a-lifetime comet.

This week's full moon is called the Hunter's Moon. It's also a supermoon, which is expected to be the brightest one of the year so far.
