The last full moon of summer will show up before the expected time Wednesday, setting up a blue moon in October.

The September full moon is generally alluded to as the harvest moon, yet this year is known as the corn moon for only one of the period’s crops.

The 2020 September full moon is just too soon to be a genuine harvest moon, as indicated by the Farmers’ Almanac, which says the title goes to the full moon nearest to the harvest time equinox, the primary day of fall, on Sept. 22.

That implies the following full moon on Oct. 1 will be the harvest moon.

Also, that thusly sets up a blue moon: A second October full moon, the hunter’s moon, will show up on Halloween, Oct. 31.

Meanwhile, the corn moon will ascend at 8:12 p.m. Tuesday and formally arrive at its full stage at 1:22 a.m. Wednesday before setting at 7:39 a.m. Sadly, as of Saturday, the Lehigh Valley climate forecast for that night calls for generally overcast skies and showers.
