What is a Harvest Moon?
In traditional skylore, the Harvest Moon is the full moon closest to the autumnal equinox, and depending on the year, the Harvest Moon can come anywhere from two weeks before to two weeks after the autumnal equinox. For us in the Northern Hemisphere, the 2015 autumnal equinox comes on September 23, so the September 27-28 full moon counts as the Northern Hemisphere’s Harvest Moon.
By the way, this year’s Harvest Moon will present the closest and largest full moon of the year. It’ll also stage a total eclipse of the moon on the night of September 27-28.
However, the Harvest Moon isn’t always the biggest full moon of the year or more pumpkin-colored than other full moons. It’s special because, at this time of year in the Northern Hemisphere, the time between successive moonrises – from one night to the next – is shorter than usual. But this year, 2015, the Harvest Moon is a bit bigger than usual … because it’s a supermoon.
What makes this moon a supermoon?
This year’s Harvest Moon qualifies as a supermoon because the moon turns full about one hour after reaching lunar perigee – the moon’s closest point to Earth for the month
