The September full moon is known as the Harvest moon. It is generally larger, and therefore appears brighter from Earth. It is the full moon closest to the autumnal equinox.

It is a “Harvest moon” because farmers used to use the light given by the seemingly larger, brighter moon in order to harvest their crops, long into the night.

I bet if you tried, you’d be able to read a book with just the light of the full Harvest Moon.

(Note: The photo featured, whilst it is the september full moon, is not a harvest moon. The harvest moon for the Southern Hemisphere occurs in March, it’s autumn.)
