A large spider wove a perfect web outside our kitchen window yesterday, giving it a deliberately-built front row seat for tomorrow’s full moon in Aries, which will rise right over our tiny garden. Tomorrow’s full moon is almost everybody’s favorite, the moon closest to the Autumn Equinox, the Harvest Moon whose light, says Waverly Fitzgerald at SchooloftheSeasons.com, has illuminated the harvest work of farmers on deadline for centuries, so ample and tireless its glorious glow.

Harvest festivities, dances, and ceremonies are also held by the light of this moon, so you’ll at least have to grab a good look (and maybe shake your booty!) at its beauty. This full moon may look much bigger than it ordinarily seems, due in part to an optical illusion called the Moon Illusion, which you can read more about here.

“During September, the relationship between the ecliptic plane (on which the planets orbit) shifts in relationship to the earth and the moon rises more or less at the same time every night for the three nights of the Harvest full moon,” says Fitzgerald, citing Christopher Dewdney’s book “Acquainted with the Night: Excursions Through the World After Dark” as a reference.
