Get ready to cry.
On the evening of the 13th Friday night, a breathtaking "harvest moon" will rise in the eastern sky, and the almost complete moon will be visible every night over the night, except for annoying clouds.
(Although the official moment of The Full Moon is actually EDT on Saturday, the 14th, at 00:33, he'll still be well-filled throughout Friday night, EarthSky said.)
It's pretty rare that on Friday, the 13th, a full moon appears. It last occurred on October 13, 2000 and will occur again on Aug. 13, 2049, according to Farmers Almanac.
Consider the following: The moon is shrinking and trembling. Is that something to worry about?
What is a harvest moon?
The harvest moon is the full moon closest to the autumn equinox, the beginning of autumn, which is September 23 this year. It differs from other full moons as it rises for several consecutive nights at about the same time and gives more light.
Why the nickname "Harvest Moon"?
"In the days before tractors with headlamps, it was crucial that the moonlight came to work quickly to bring in the harvest before rain rotted them," said Alan MacRobert editor of Sky & Telescope magazine.
According to NASA, many crops ripen in late summer and early autumn, causing farmers to be extremely busy at this time of year. They had to work after sunset. The moonlight became an integral part of agriculture and so the harvest moon was born.
It's also a "micromond"!
This month's full moon is also an unusually small full moon: on Friday, the Moon will reach "Apogee," the farthest point of its orbit around Earth, hence the nickname "Micromoon," Astronomy Magazine reports It reaches 252,511 miles to the center of the Earth.
At its peak, the full moon appears to be 14% smaller than Earth's for Earth's people, making it a micromond, HuffPost reports, this is the opposite effect of the famous "Supermoon," when the moon is as close as possible to the earth.

Full moon, then, human behavior?
If you feel squeamish on Friday night, blame the combination of Triskaide caphobia (fear of number 13) and lunar effects ng that there is a connection between lunar cycles and human behavior. According to AccuWeather reports, the full moon has even been associated with strange or crazy behavior, including suicide, sleepwalking and violence.
