After sunset around the time of any full moon, the moon will always be near the horizon. Many people look for it shortly after sunset around the time of full moon. That’s because the Harvest Moon has such a powerful mystique. Still, in any year, you might think the Harvest Moon looks bigger or brighter or more orange. In 2021, it’s pretty much an average-sized full moon. No, the full Harvest Moon is not necessarily closer than any other full moon. But five years ago – Septem– the Harvest Moon was the year’s closest and biggest supermoon. In 2019, the Harvest Moon was actually a micro-moon or mini-moon: the most distant and smallest full moon of the year 2019. Last year, in 2020, the Harvest Moon was the second-smallest full moon of 2020. Is the Harvest Moon bigger, or brighter or more colorful?īecause the moon’s orbit around Earth isn’t a perfect circle, the Harvest Moon’s distance from Earth – and apparent size in our sky – differs from year to year. Werburgh’s Church in Spondon, Derby, on October 1. captured the full Harvest Moon showing off the weathervane of St. So there is no long period of darkness between sunset and moonrise. The narrow angle of the ecliptic means the moon rises noticeably farther north on the horizon from one night to the next. Why does this happen? Check out the illustrations below: In autumn, the ecliptic – marking the moon’s approximate path across our sky – makes a narrow angle with the evening horizon. The moon will rise during or near twilight on these nights, presenting dusk-till-dawn moonlight for several nights in a row around the time of the Harvest Moon. But it means that, in the nights after a full Harvest Moon, you’ll see the moon ascending in the east relatively soon after sunset. The difference between 50 minutes and 25 minutes might not seem like much. For instance, at Anchorage, Alaska ( 61 degrees north latitude) the moon will rise at nearly the same time for a week! The farther north you live, the greater the Harvest Moon effect. For mid-temperate latitudes, it rises only about 20 to 25 minutes later daily for several days before and after the full Harvest Moon.įor very high northern latitudes, there’s even less time between successive moonrises. But when a full moon happens close to an autumn equinox, the moon on the following nights rises closer to the time of sunset. On average, the full moon rises around sunset, and rises about 50 minutes later each day. Nature is particularly cooperative in giving us dusk-till-dawn moonlight, for several evenings in a row, around the time of the Harvest Moon. But these autumn full moons do have special characteristics related to the time of moonrise. In some ways, it’s like any other full moon name. By popular acclaim, most regard a Blue Moon as the second of two full moons in one calendar month. Therefore, some people refer to the third of these four full moons as a seasonal Blue Moon.Īctually, that definition of Blue Moon preceded the better known definition.

That’s the fourth moon of summer for the Northern Hemisphere, and the fourth winter full moon for the Southern Hemisphere.įor the Southern Hemisphere, the Harvest Moon always comes in March or early April. This year, the September full moon is the fourth of the season’s four full moons. The Harvest Moon is either the last full moon of the summer season, or the first full moon in autumn. Thus, for the Northern Hemisphere, this full moon – the full moon closest to our autumn equinox – is our Harvest Moon.ĭepending on the year, the full Harvest Moon can occur anywhere from two weeks before the autumn equinox to two weeks after. The full moon falls less than two days earlier, on September 20. In 2021, the Northern Hemisphere autumn equinox comes on September 22.
