Harvest Moon To Rise Over New Jersey Tonight

It’s not a supermoon — the phenomenon when a moon appears larger than it is — but the harvest moon will be something special over the next several nights. The harvest moon, which NASA says often looks like a great pumpkin, reached its full phase at 2:40 p.m. Thursday, but it will rise over the region just before 7 p.m.

Cloudy skies and scattered showers Thursday night, though, may spoil the best views.

Among astronomers, the harvest moon is the full moon closest to the autumn equinox, which occurred this year on Sept. 22. For that reason, this year’s September full moon went by some of the other monikers — the corn moon, the fruit moon or the barley moon in North America.

And, usually, October’s full moon is known as the hunter’s moon and, less frequently, the blood moon or the sanguine moon, according to nightskyinfo.com.

Though the harvest moon hasn’t fallen in October since 2009, it’s not all that rare, either, Ernie Wright, a specialist at the NASA Goddard Space Flight Center’s Scientific Visualization Studio in Maryland, told National Geographic.

A harvest moon can happen on any date from Sept. 7-Oct. 8, according to the regular 29.5-day cycle of the moon, Wright said.

Regardless of what they’re called, autumn full moons are special. Earthsky.org explains it:

“Around the time of the autumn equinox, the ecliptic — or the path of the sun, moon, and planets – makes a narrow angle with the horizon at sunset. “Every full moon rises around the time of sunset, and on average each successive moonrise comes about 50 minutes later daily. But, on September and October evenings – because of the narrow angle of the ecliptic to the horizon — the moon rises sooner than the average. “So, instead of rising 50 minutes later in the days after full moon, the waning gibbous moon might rise only 35 minutes later, or thereabouts, for several days in a row (at mid-northern latitudes). At far northern latitudes — like at Fairbanks, Alaska — the moon rises about 15 minutes later for days on end.”

This was important in the days before tractors and combines with lights, because it meant they could harvest under the moonlight.
