Partial lunar eclipse September 17-18, 2024

[ad_1]

On the night of September 17-18, 2024, the Earth, the sun and the Super Harvest Moon will line up in space, causing a lunar eclipse. The eclipse will be far from total. At mid-eclipse, only 8% of the moon will lie in Earth’s dark shadow. Still, the EarthSky team – in cooperation with our friends at TimeandDate.com – will have fun watching the eclipse LIVE beginning at 8:45 p.m. CDT on September 17 (1:45 UTC on September 18). We’ll be talking about why this September full moon is a Super Harvest Moon, about how eclipses prove the Earth is round, and more. Join us for an eclipse watch party!

People in the Americas, parts of Antarctica, the western Indian Ocean, the Middle East, Africa, Europe, the Atlantic Ocean, and eastern Polynesia will see a shallow partial lunar eclipse overnight on September 17-18, 2024. The steady golden light near the eclipsed moon will be the planet Saturn.

The whole half of Earth facing the full moon – that is, the whole half of Earth that’s in nighttime – will see the lunar eclipse. Of course, lunar eclipses are safe to view with the unaided eye. Binoculars and telescopes aren’t required to view a lunar eclipse, but they do enhance the view.

At this eclipse, only a small fraction of the moon will enter Earth’s dark umbral shadow. For the most part, the September 17-18, 2024, lunar eclipse will appear as a penumbral eclipse of the moon. In other words, as the eclipse progresses, you should notice a dark shading on the moon (Earth’s penumbral shadow), followed by the barest of dark bites (Earth’s dark umbral shadow) taken from one edge of the moon.

And don’t forget Saturn! It’s the bright object near the moon on September 17-18.

When the lunar eclipse occurs worldwide

Penumbral eclipse begins at 0:41 UTC on September 18, 2024. Earth’s lighter penumbral shadow will begin crossing the moon’s face. You probably won’t notice it at first. But, as the eclipse progresses, you should see a subtle shading on the moon.
Partial eclipse begins at 2:12 UTC on September 18, 2024. Now it’ll appear as if a tiny, but dark, bite is taken from one edge of the moon.
Greatest eclipse at 2:44 UTC on September 18, 2024. Only a small portion of the moon – about 8% – will be eclipsed by Earth’s dark shadow.
Partial eclipse ends at 3:16 UTC on September 18, 2024.
Penumbral eclipse ends at 4:47 UTC on September 18, 2024.
Note: A bright “star” will appear near the eclipsed moon. It’s really a planet, Saturn.

Nikolaos wrote: “A collage of tonight’s partial lunar eclipse. The photos were shot at hours UTC, 19:45, 20:00 and 20:15, from start to maximum cover by the Earth’s shadow.” Thank you, Nikolaos!

How long will it last?

From start to finish, the eclipse will last 246 minutes. And the moon will be in Earth’s dark shadow – for the partial eclipse – for only 64 minutes.

Diagram of the sun on left, Earth in the middle casting shadow, moon in shadow on right. — During a lunar eclipse, Earth’s shadow falls on the moon. So if the moon passes through the dark central shadow of Earth – the umbra – a partial or total lunar eclipse takes place. But if the moon only passes through the outer part of the shadow (the penumbra), a subtle penumbral eclipse occurs. Diagram via Fred Espenak’s Lunar Eclipses for Beginners. Used with permission.

Who can see lunar eclipses?

A full moon is up only at night. And a total lunar eclipse is visible from all parts of Earth that are experiencing night while the eclipse is taking place. But some will see the eclipse more clearly, or more thoroughly, than others, depending on location. For example, some will see it at moonrise or moonset, when the moon is low in the sky.

The constellation behind the partial lunar eclipse

The September 17-18, 2024, partial lunar eclipse occurs when the moon is in the constellation of Pisces the Fish.

Chart showing the moon in eclipse and where it's visible from. — A map for the partial lunar eclipse on September 17-18, 2024. It sweeps across the Americas, parts of Antarctica, the western Indian Ocean, the Middle East, Africa, Europe, the Atlantic Ocean, and eastern Polynesia. Areas in white on the map will see all of the partial eclipse. The line down the middle notes where the greatest eclipse occurs. Shaded areas will see part of the eclipse and dark areas are where the eclipse is not visible. Note the difference between UTC and TD (terrestrial dynamical time, often abbreviated TT as well).
