Ok, so I missed this month’s full moon by a week, but technically I missed the Harvest Moon by a month.
Meaning: The harvest moon is the moon at or about the period of fullness that is nearest to the autumnal equinox. The harvest moon is often mistaken for the modern day hunter's moon.
Origin: All full moons rise around the time of sunset. In general the moon rises about 50 minutes later each day. As it moves in orbit around Earth, the Harvest Moon and Hunter's Moon are special because, around the time of these half moons, the time difference between moonrise on successive evenings is shorter than usual. This means that the moon rises approximately 30 minutes later from one night to the next, as seen from about 40 degrees N. or S. latitude. Thus, there is no long period of darkness between sunset and moonrise around the time following these full moons. In times past this feature of these autumn moons was said to help farmers working to bring in their crops (or, in the case of the Hunter's Moon, hunters tracking their prey). They could continue being productive by moonlight even after the sun had set. Hence the name Harvest Moon.
The harvest moon comes soon before or soon after the autumnal equinox. It is simply the full moon closest to that equinox. About once every four years it occurs in October (in the northern hemisphere), depending on the cycles of the moon. Currently, the latest the harvest moon can occur is on October 7. When the night of the harvest moon coincides with the night of the equinox, it is called a "Super Harvest Moon." In 2010 in the contiguous United States, the harvest moon happened in the early morning hours of Sept 23, only 5 1/2 hours after the autumnal equinox, creating the first Super Harvest Moon since 1991.
Why does the Harvest Moon seem larger? The apparent larger size is because the brain perceives a low-hanging moon to be larger than one that's high in the sky. This is known as a moon illusion and it can be seen with any full moon. It can also be seen with constellations; in other words, a constellation viewed low in the sky will appear bigger than when it is high in the sky.
