As time moves forward in the lunar cycle, the moon’s visibility diminishes progressively.

The lunar cycle comprises eight unique phases regarding the moon’s visibility. This cycle spans roughly 29.5 days, according to NASA, and these phases transpire as the Sun shines on various portions of the moon while it circles the Earth.

So, what is the status of the moon this evening, Aug. 13?

What is the current moon phase?

On Wednesday, Aug. 13, the current moon phase is Waning Gibbous, with 79% illumination as viewed from Earth, per NASA’s Daily Moon Observation.

This evening marks the second night of the peak of the Perseids Meteor Shower. The light from the moon may obscure some meteors, yet others should still be visible as this celestial spectacle brightens the night sky.

Moreover, without any visual equipment, you can observe the Tycho Crater, Mare Serenitatis, and the Oceanus Procellarum, also known as the “Ocean of Storms,” which covers over 10% of the moon’s surface.

Using binoculars, you might also be able to spot the Clavius Crater, Alphonsus Crater, and Mare Frigoris. Through a telescope, the Apollo 11 landing site, Rima Ariadaeus, and the Linne Crater become visible.

When will the next full moon be?

The next full moon is set to occur on Sept. 7. The previous full moon took place on Aug. 9.

What do moon phases mean?

According to NASA, the phases of the moon arise from the 29.5-day cycle of the moon’s orbit, which alters the angles between the Sun, Moon, and Earth. Moon phases signify how we perceive the moon from Earth as it orbits around us. We consistently see the same side of the moon, but the Sun-lit portion varies depending on its positional relationship in orbit. This leads to full moons, half moons, and moons that are entirely dark. Eight primary moon phases exist, following a cyclic pattern:

New Moon – The moon is placed between the Earth and the Sun, meaning the visible side is dark (invisible to the observer).

Waxing Crescent – A thin sliver of light appears on the right side (for those in the Northern Hemisphere).

First Quarter – The right side of the moon is half illuminated, resembling a half-moon.

Waxing Gibbous – More than half is lit up, though not yet complete.

Full Moon – The entire surface of the moon is lit and completely observable.

Waning Gibbous – The moon starts to lose illumination on the right side.

Last Quarter (or Third Quarter) – Another half-moon appears, with the left side illuminated.
