Take a look up tonight and chances are you’ll see the Harvest Moon. A Harvest Moon is defined as the full moon closest to the autumnal equinox which this year is on September 22nd.
According to Weather.com’s Michele Burger, unlike the Blue Moon back in August, the Harvest Moon behaves differently than a typical full moon. “Throughout the year, the moon rises, on average, about 50 minutes later each day,” according to NASA Science News. “But near the autumnal equinox … the day-to-day difference in the local time of moonrise is only 30 minutes.” Why does that matter? Simply put, agriculture.
“In the days before electric lights, farmers depended on bright moonlight to extend the workday beyond sunset,” wrote NASA’s Dr. Tony Phillips. “It was the only way they could gather their ripening crops in time for market. The full moon closest to the autumnal equinox became the Harvest Moon, and it was always a welcome sight.”
Back in 2010, there was a Super Harvest Moon — the first one in two decades and the last until 2029 — when the seasonal lunar event happened on the night of the autumnal equinox, offering what Phillips describes as “maximum illumination.”
