A partial lunar eclipse is set to unfold around Raksha Bandhan 2026, bringing an unusual astronomical occurrence to the same period as the Hindu festival. This striking celestial event is particularly noteworthy because of how deeply the Moon will move into Earth's shadow, making it one of the year's most interesting sky events.

When Is The Partial Lunar Eclipse 2026?

The Partial Lunar Eclipse 2026 will take place on August 27-28, depending on the time zone. In Universal Time, the eclipse occurs on August 28.

According to NASA, the penumbral phase begins at 1:23 UTC, while the partial phase starts at 2:33 UTC. The eclipse reaches its maximum at 4:13 UTC, with the partial phase ending at 5:52 UTC. The penumbral phase concludes at 7:02 UTC.

For India, this translates approximately to:

• Penumbral eclipse begins: 6:53 AM IST
• Partial eclipse begins: 8:03 AM IST
• Greatest eclipse: 9:43 AM IST
• Partial eclipse ends: 11:22 AM IST
• Penumbral eclipse ends: 12:32 PM IST

Why Is This A Deep Partial Lunar Eclipse?

A lunar eclipse occurs when Earth comes between the Sun and Moon, causing Earth's shadow to fall on the Moon.

During a partial lunar eclipse, only part of the Moon enters Earth's umbra, the darkest central portion of Earth's shadow. Since the entire lunar disk does not enter the umbra, the eclipse remains partial.

What makes the August event unusual is its depth. At maximum eclipse, around 93% of the Moon's diameter will enter Earth's umbra, making it a particularly deep partial eclipse. When measured by the area of the lunar disk, the figure is approximately 96%.

Will The Partial Lunar Eclipse Be Visible In India?

Despite the eclipse coinciding with Raksha Bandhan, it will not be visible from India.

The reason is straightforward: the eclipse takes place when the Moon is below the horizon for observers in India. The relevant eclipse phases occur during daytime hours in the country.

Therefore, Indian skywatchers will not be able to observe the Moon passing through Earth's shadow.

What Makes The August 2026 Eclipse Special?

The event stands out because it comes remarkably close to totality while remaining technically a partial lunar eclipse. With roughly 93% of the Moon's diameter entering the umbra, only a small portion of the lunar disk will escape Earth's darkest shadow.

Its coincidence with Raksha Bandhan and Shravana Purnima makes the August 2026 eclipse particularly noteworthy for Indians, even though the eclipse itself cannot be seen from India.

Where Will The Eclipse Be Visible?

The August 2026 lunar eclipse will be visible from large parts of North America, South America, Europe and Africa, although the exact phases visible will depend on location.

Some places will see the eclipse around moonrise or moonset, while observers in other regions will be able to watch much of the event from start to finish.

How Will The Moon Look?

As the Moon moves into Earth's umbra, a large portion of its surface will become considerably darker.

Because this is such a deep partial eclipse, only a small portion of the lunar disk will remain outside the umbra at maximum eclipse. The eclipsed portion can also take on coppery or reddish-orange shades as sunlight passes through Earth's atmosphere before reaching the Moon.

Is It Safe To Watch A Lunar Eclipse?

Yes. Lunar eclipses are safe to observe with the naked eye, and special protective glasses are not required.

Where the eclipse is visible, binoculars or a telescope can offer a more detailed view of Earth's shadow moving across the Moon.

A Celestial Event To Watch From The Right Places

The August 27-28, 2026 partial lunar eclipse promises an impressive view for skywatchers in regions where the Moon is above the horizon. Its unusually deep passage through Earth's shadow will make the event stand out among the year's lunar phenomena.

For India, the significance lies in its coincidence with Raksha Bandhan, while the actual eclipse will unfold beyond the country's visible night sky.
