The next full Moon will be tomorrow, Thursday afternoon, Oct. 1, at 5:05 p.m. The moon will appear to be “opposite” the Sun (in Earth-based longitude). Enjoy this one, because it will seem to be full for about three days around this time, from Wednesday morning through Saturday morning.

As the full moon closest to the autumnal equinox (the end of summer and start of fall), this is the Harvest Moon. During the harvest season farmers sometimes need to work late into the night by the light of the Moon. The full Moon rises an average of 50 minutes later each night, but for the few nights around the Harvest Moon, the Moon seems to rise at nearly the same time: just 25 to 30 minutes later across the northern USA, and only 10 to 20 minutes later farther north in Canada and Europe.

The Harvest Moon is an old European name with the Oxford English Dictionary giving 1706 as the year of its first published use. Most years the Harvest Moon falls in September but this is one of the years it falls in October.


October 2020 has two full moons and is known as a Blue Moon month.

The first full moon rises tomorrow, Oct. 1. The second, the “Blue Moon” is on Oct. 31.

Currently, the term Blue Moon is used for the second of two full moons in a single calendar month. An older definition of Blue Moon is that it’s the third of four full moons in a single season.

Whichever definition you choose to accept, this week’s moon should be glorious.
