Skywatchers, look up: The night sky promises another spectacular show. The annual Hunter's Moon peaks Monday and Tuesday, Oct. 26 and 27, in the Northern Hemisphere.
The full moon officially arrives at 12:05 UTC, or 8:05 a.m. EDT the morning of Oct. 27. That means that the moon you'll see Monday night will be just as full as Tuesday's orb, even though Tuesday's moon will have officially started waning, .

This year's Hunter's is , meaning it's near perigee, the moon's closest point to Earth during its monthly trip around our planet. Because of this supermoon status, the full moon should appear about 14 percent larger, a subtle amount to the amateur field, EarthSky noted. It should look brighter, and it should appear orange if you catch it close to the horizon. (However, note that supermoon is not an official astronomical term.)
The Hunter's Moon occurs annually; it's the next full moon after the Harvest Moon, or the full moon closest to the autumnal equinox. ( marked a particularly rare event, thanks to a simultaneously total lunar eclipse.)
Like the Harvest Moon, the Hunter's Moon name comes from the idea that the full orb's extra light helped humans work into the night. “Hunters … tracked and killed their prey by autumn moonlight, stockpiling food for the winter ahead,” NASA’s Tony Phillips wrote in 2013. “You can picture them: Silent figures padding through the forest, the moon overhead, pale as a corpse, its cold light betraying the creatures of the wood.”
Although orange Harvest Moons typically garner the most attention, of the year has a moniker, derived from Native American names, according to Space.com. Next up: the Beaver Moon or frosty moon on Nov. 25.
