What Is the Harvest Moon and What Does It Mean? Before the Fall Equinox in September 2021, the Full Moon will rise.
A full “Harvest Moon” will be seen tonight, only two days before the Northern Hemisphere’s autumn equinox.
The term “full moon” describes the point in time when the Earth is directly between the sun and our natural satellite.
The face of the moon that we can view from Earth is totally lighted at these times, and it appears to be a perfect circle.
The moon is technically full for only a fraction of a second. This occurs around 7:54 p.m. EDT on September 20 for the forthcoming Harvest Moon, for example.
However, from Sunday to Tuesday, the moon will look completely lighted in the night sky to most casual viewers.
The full moon closest to the autumn equinox in the Northern Hemisphere is known as the “Harvest Moon” in the Northern Hemisphere.
The word “Harvest Moon” is distinct from other traditional full moon names, which are all linked to a particular month.
While most Harvest moons occur in September, depending on how the lunar cycle aligns with the Gregorian calendar, this moniker is sometimes given to a full moon in October.
The Earth’s axis, which is inclined at an angle of roughly 23.4 degrees relative to the plane of its orbit around the sun, is neither directed towards nor away from the sun during the Northern Hemisphere’s fall equinox.
The sun shines directly over the equator at this moment, and day and night are about equal in length. In astronomical terms, the September equinox marks the start of fall in the Northern Hemisphere.
Each year, the fall equinox occurs between September 21 and September 24. The autumn equinox falls on September 22 in 2021.
Full moon names come from a variety of locales and periods in history, including Native American, colonial American, and European sources.
