Although it's technically possible to look at the Harvest Moon when it's 100% lit, that's not the time to observe it. This shortens the period between the time the sun sets and the moon rises.And like any full moon, the sun and moon are opposite each other, so the sun cranks up the moon's brightness.

The full moon of September, known as the "harvest moon", will soon be glowing in the almost-autumn sky.

"The harvest moon has always been a traditional one because it was an important time to know when to start harvesting before the snow flies and the crops have done as much growing as they're going to do". NASA says the moon will appear full again Saturday night into Sunday morning. Hence one of its nicknames: micro moon. It's the opposite of a supermoon. It turns out that the moon actually has a chance to be a Supermoon or Micromoon - all great reasons to tune in and check out the sky that night. For some, a full moon is considered bad luck similar to walking under a ladder or breaking a mirror.

For most of the nation, the September moon will be full before midnight on Friday. A song called "Shine On, Harvest Moon" was penned in 1908 by vaudeville stars Nora Bayes and Jack Norworth.
