Admire the rare "Super Blood Moon" phenomenon in Vietnam

This total solar eclipse occurred just a few days before the Moon reached its perigee, making it appear larger than usual. This was not only an amazing astronomical phenomenon but also a special light show in the sky of Vietnam.

On the night of Sunday, September 7 and early morning of Monday, September 8, 2025, astronomy lovers around the world will witness a rare phenomenon: a total lunar eclipse, also known as the “Blood Moon”. Notably, Vietnam is in the clearest observation area, promising to bring a spectacular scene in the sky.

Observation time in Vietnam

The phenomenon will start from the end of September 7 and last until the early morning of September 8 with specific milestones:

Penumbral eclipse begins: 22:28 September 7

Start of total phase (Moon turns completely red): 00:30 September 8

Maximum: 01:11 on September 8

Total phase end: 01:52 September 8

End of phenomenon: 03:55 September 8

Thus, the entire eclipse will last more than 5 hours and 27 minutes, of which the most brilliant "Blood Moon" part will last for about 82 minutes.

Why does the moon turn red?

When the Moon enters the Earth’s shadow, sunlight is refracted and scattered by the atmosphere. Short-wavelength rays are filtered out, leaving only red-orange light shining on the Moon’s surface, creating the mysterious “Blood Moon” phenomenon.

Notably, this eclipse occurs just a few days before the Moon reaches perigee – the closest position to Earth in its orbit – so the Moon will be larger than normal, creating a scene commonly known as the “Super Blood Moon”.

Vietnam observes favorably

People across the country can watch this total solar eclipse in its entirety if weather conditions are favorable. The best time is from 00:30 to 01:52 on September 8, when the Moon is completely submerged in the Earth's shadow and glows a deep red.

For observers in Asia and Australia, including Vietnam, the Moon will be high in the sky – ideal for viewing and photography.

Tips for observing

No need for goggles, can be observed with the naked eye.

Prepare binoculars or a camera to capture sharper images.

Choose an open space with little artificial light, such as the suburbs, rural areas or high areas.

Astronomical events to look forward to

“Blood Moon” is not only an amazing astronomical phenomenon but also brings a special experience to those who love the night sky. This is one of the rare events, when the Moon is both larger than usual and has a brilliant red color, turning the sky into an unforgettable magical scene.

The night of September 7-8, 2025 will certainly be an unforgettable milestone for the Vietnamese astronomy community, as well as millions of people around the world.
