The September full Moon or “Harvest Moon” used to be a celestial boon for farmers. Because it rises soon after sunset, they could continue reaping their crops by its light until late, hence the name. It is also the full Moon closest to the autumnal equinox (September 23rd this year), the astronomical onset of autumn, when the sun is directly above the equator and day and night are of equal length. Coincidentally, this Harvest Moon will also be a “micro-moon”, because it is at the farthest point from Earth in its orbit. This means it will appear 14% smaller than February’s “supermoon”. Although the full Moon’s peak above America’s east coast and Britain will be after midnight—and so technically on Saturday morning—for the superstitious at least there is something portentous about its rising on the night of Friday the 13th. Particularly as, according to paranormal types, the Harvest Moon imbues werewolves with increased power.
Watch out for werewolves!
