The most spectacular Full Moon is coming on October 1-2, 2020. Don't Miss the Full Harvest Moon. According to folklore, the Harvest Moon is the Full Moon that falls closest to the autumnal equinox, the beginning of northern autumn. In the days before light bulbs, farmers relied on moonlight to help them harvest their crops. Many crops ripen all at once in late summer and early autumn, so farmers found themselves extremely busy at this time of the year. They have to work after sundown. Moonlight became an essential part of farming and thus, the Harvest Moon was born. There's more to the Harvest Moon, however, than just an old-fashioned name. It realy is special. Throughout the year the Moon rises, on average, about 50 minutes later each day. But near the Equinox, this difference shrinks to only 30 minutes. The reason is, at the beginning of autumn the Moon's orbital path makes a narrow angle with the evening horizon. For several nights in a row around the time of the Harvest Moon, the Moon rises almost at sunset. And you know what happens when the Moon rises at sunset? Low-hanging Moons are reddened by clouds and dust. Not only that, they are swollen to outlandish size by the Moon illusion, a well known but still mysterious trick of they eye, that makes low-hanging Moons seem much larger than they really are. When you add these effects together the Harvest Moon often looks like a great pumpkin. The experience is repeated for several nights in a row around the Equinox. A great pumpkin-colored Moon rising in the east is a nice way to end the day. At sundown on October 1-2, go outside, face east and enjoy the Harvest Moon. Stay Tuned!
