On the night of 7 September 2025, Singaporeans will be treated to a Total Lunar Eclipse – a rare celestial phenomenon where the Earth slips directly between the Sun and Moon, casting its shadow over the lunar surface.

As the eclipse unfolds between 11.28pm on 7 September and 4.55am on 8 September, the Moon will undergo a gradual transformation, with the “blood moon” peak occurring between 1.30am and 2.52am. During this time, the Moon will take on a rich reddish-orange hue, caused by sunlight filtering through Earth’s atmosphere and scattering away shorter wavelengths like blue.

Here are the key details:

  • Peak Activity: The Total Lunar Eclipse will unfold from 11.28pm on 7 September until 4.55am on 8 September.
  • Best Viewing Time: The eclipse will reach its maximum phase between 1.30am and 2.52am.
  • Where to Watch: The eclipse will be visible across Singapore, as the Moon will be high overhead – just find a spot with a clear view of the sky.
  • No Equipment Required: The spectacle is safe and best enjoyed with the naked eye.


About Lunar Eclipses

1. What are lunar eclipses and why do they occur?

A lunar eclipse happens when Earth slips perfectly between the Sun and the Moon, casting its shadow across the Moon’s face. In contrast, a solar eclipse is when the Moon takes centre stage, gliding in front of the Sun and momentarily hiding its light from view.

2. What is the difference between a total, partial, and a penumbral lunar eclipse?

A total lunar eclipse happens when the Moon plunges fully into Earth’s umbra – the darkest core of our planet’s shadow. Here, the Moon takes on a dreamy red or orange glow because Earth’s atmosphere scatters away shorter wavelengths like blue, letting the longer, warmer tones slip through. The dustier the air, the redder the Moon’s makeover. The celestial event on 7 September will be a total lunar eclipse.

A partial lunar eclipse is where the Sun, Earth, and Moon don’t line up perfectly, so only a portion of the Moon slips into the umbra. You’ll see Earth’s shadow creeping across, then sliding away, never fully cloaking the Moon.

A penumbral lunar eclipse is when the Moon drifts only through Earth’s penumbra, the pale outer shadow. The dimming is so gentle, you might not even notice unless you’re looking for it.

3. How often do lunar eclipses occur?

A few times a year – between one to four times – our Earth, Moon, and Sun strike just the right pose to stage a spectacular celestial shadow show: the eclipse. Because the Moon’s orbit is tilted in relation to Earth’s path around the Sun, these events are occasional delights rather than a monthly occurrence.

Total Lunar Eclipse taking place 7 September

1. When will the Total Lunar Eclipse take place?

The Total Lunar Eclipse will begin on 7 Sep 11.28pm, stretching to 8 Sep 4.55am, and the maximum eclipse (blood moon) occurs from 1.30am to 2.52am.

2. What can we expect to see during the Total Lunar Eclipse?

During a Total Lunar Eclipse, the Moon will undergo a gradual yet dramatic transformation. As the Earth moves directly between the Sun and the Moon during the full moon phase, its shadow will steadily cover the lunar surface. Over the course of several hours, the Moon’s brightness will dim before taking on a rich, reddish hue, a result of sunlight filtering through Earth’s atmosphere and scattering shorter wavelengths of light. This phenomenon will be visible from approximately half of Earth, offering a rare and striking spectacle for observers within the viewing region.

3. When was the last Total Lunar Eclipse visible in Singapore?

The last Total Lunar Eclipse visible from Singapore took place on 8 November 2022, which means the upcoming eclipse will be the first in nearly three years that can be observed locally.

While a Total Lunar Eclipse occurred on 14 March 2025, it was not visible from Singapore due to our geographical position.




4. How can I get the best view of this occurrence in Singapore?

The Total Lunar Eclipse can be viewed almost anywhere in Singapore as it will happen when the Moon is overhead. Singapore’s weather conditions and frequent cloud cover can also affect visibility of this occurrence. As such, observers should also check the weather forecast for clear skies.

5. Is any special equipment required to view this?

No special equipment is required to view this as the Total Lunar Eclipse will be visible to the naked eye.

6. Will the Science Centre Observatory (SCOB) hold a viewing session for the Total Lunar Eclipse?

The Observatory at Science Centre Singapore will not be holding a specific viewing session for the Total Lunar Eclipse. However, on selected Fridays, astronomy enthusiasts can take part in stargazing sessions held by The Observatory for a unique chance to explore the solar system and observe stars and planets up close through a telescope. Learn more about these sessions here.
