What is a Harvest Moon?

According to Time and Date, the Harvest Moon is the Full Moon that occurs closest to the autumnal equinox which happens in either September or October. This year's autumnal equinox for Ireland will occur on September 23 at 8:50 am.

Old Moore's Almanac points out that the tradition of celebrating the Harvest Moon originated in Europe, as it allowed farmers extra moonlight after the days had shortened to harvest their crops.

What is a Micro Moon?

According to Time and Date, “a Micro Moon happens when a Full Moon or a New Moon coincides with apogee; the point in the Moon's orbit farthest away from Earth.”

Coincidentally, Ireland’s Harvest Moon will also be a Micro Moon this year.

Smithsonian notes that the Harvest Moon typically appears large and orange, but since this year it will be a Micro Moon, it will appear unusually small, about 14 percent smaller, and far away.

Later this month, Ireland will be treated to a Super Moon, the opposite of a Micro Moon, on September 28.
