The harvest moon is the full moon closest to the autumnal equinox (in the northern hemisphere). It is the first full moon closest to that equinox. About once every four years it occurs in October, depending on the cycles of the moon.
The harvest moon seems to be bigger, brighter and more colourful than other full moons. This caused by light from the moon passing through an increased number of dense atmospheric particles, which creates an illusion. The atmosphere refracts the moonlight (which is really reflected white light from the sun), and this allows the reddish component of the light to be seen.
Blessed be the goddess who watches over us and who lovingly gifts us visions and dreams and speaks to us through our intuition.
May your night be touched with magick
love light and hugsCara
