On the evening of September 17th, a full moon will fill the Montana sky.

But this full moon isn't just any full moon; it is called the Harvest Moon.

When Is The Harvest Moon?

The Harvest Moon is expected to peak at 10:34 PM Eastern or 8:34 PM here in Montana.

This year's Harvest Moon is unique because it will also be a supermoon, which means it will be larger and brighter than a typical full moon.

This is due to the moon's orbit being closer to Earth.

Storms are expected to start moving in on Tuesday night, which may hinder the moon's visibility, but a few clouds may also provide some epic shots!

Partial Lunar Eclipse

In addition to this year's Harvest Moon, there will also be a partial lunar eclipse.

This natural phase occurs when the earth passes between the sun and moon, causing a shadow.

This makes the moon appear darker and a bit red.

According to NASA, the partial lunar eclipse will begin at 6:41 PM Mountain time, with a full shadow occurring around 8:13 PM.

Why Is It Called the Harvest Moon?

Referring to this phase of the moon as a Harvest Moon is rooted in various traditions and origins, but ultimately, it boils down to agriculture.

During this time of the year, the moon rises right after sunset for several nights, and the bright moonlight allows farmers to stay in the field a bit longer and continue harvesting crops into the evening hours.

Hence the name harvest moon.
