Watch the super full moon on Sept. 17 to catch a glimpse of the partial lunar eclipse

A partial full moon is part of tonight’s full moon spectacular, adding to what already promised to be a worthwhile view.

Here’s what you need to know.

Full moon details

The next full moon, a harvest moon, will be visible at 10:34 p.m. Sept. 17, followed by the last quarter moon 2:50 p.m. Sept. 24., according to TimeandDate.com.

September’s harvest moon is also the second supermoon of the year, the second of four consecutive ones, according to NASA.

What is a supermoon?

Throughout the year, you might hear that a supermoon is in store -- a moon that occurs when a full moon or new moon is at its closest point to Earth, called perigee.

"A supermoon exceeds the disk size of an average-sized Moon by up to 8% and the brightness of an average-sized full Moon by some 16%," according to the Old Farmer's Almanac . "You may not perceive the difference in size, but a supermoon will appear brighter in the sky.”

Not every supermoon is a full moon, but if it happens to be, it is called a super full moon.

What is a partial lunar eclipse?

A lunar eclipse is one of two types of eclipses; the other is a solar eclipse. During a lunar eclipse, Earth’s shadow obscures the moon, according to NASA .

“Lunar eclipses occur at the full moon phase. When Earth is positioned precisely between the Moon and Sun, Earth’s shadow falls upon the surface of the Moon, dimming it and sometimes turning the lunar surface a striking red over the course of a few hours. Each lunar eclipse is visible from half of Earth,” said NASA.

The three types of lunar eclipses are a total lunar eclipse, a partial lunar eclipse and a penumbral lunar eclipse. During a partial lunar eclipse, an imperfect alignment of the sun, earth and moon results in the moon passing through only part of Earth’s umbra (the region of total shadow). The shadow gets bigger, then smaller, without ever covering the entire moon.

Partial lunar eclipse on Tuesday night

NASA reports that Tuesday’s super full moon will also be a partial lunar eclipse. The moon will enter Earth’s partial shadow at 8:41 p.m., but the slight dimming of the moon will be too difficult to notice until the top edge of the moon enters the full shadow at 10:13 p.m.

The eclipse will peak at 10:44 p.m. with only the top 8% of the moon in full shadow. The moon will finish exiting the full shadow at 11:16 p.m., followed by the partial shadow at 12:47 on Sept. 18, said NASA.

During the eclipse, the moon will turn a murky reddish-brown color, reports Space.com.

After Tuesday night's partial lunar eclipse, the next lunar eclipse won’t occur until a total lunar eclipse on March 14, 2025. Until then, an annular solar eclipse on Oct. 2, known as the “ring of fire,” will be the next big sky event to look forward to. It will be visible over southern Chile, southern Argentina and part of the Pacific Ocean.
