This year's Lantern Festival will have an extra celestial bonus as lanterns illuminate the night sky and families assemble to commemorate the conclusion of the Lunar New Year festivities. On Tuesday night, February 24, there will be a rare total lunar eclipse, also known as a "blood moon," which will give the festive mood a striking red glow.
When the moon rises at roughly 5:50 pm, the eclipse will already be in progress, according to Taiwan's Central Weather Administration (CWA). As the moon rises above the horizon and is partially obscured by Earth's shadow, early observers will notice that a portion of its surface has darkened.
During the total phase of the eclipse, which is expected to last from 7:04 pm to 8:03 pm and peak at 7:34 pm, the moon will turn a deep reddish-copper colour. Sky watchers will have plenty of time to observe the gradual shift during the eclipse, which will last for a total of four hours and thirty-five minutes.
When Earth moves straight between the sun and the moon, it blocks sunlight and casts a shadow over the lunar surface, causing a total lunar eclipse. Because sunlight bending through Earth's atmosphere filters out shorter blue wavelengths, the moon appears red during totality, giving it a coppery hue. This phenomenon is known as the "blood moon."
On September 7 of last year, Taiwan saw its last total lunar eclipse. After this event, the next total lunar eclipse fully visible from Taiwan will not occur until December 31, 2028, making next week's display a relatively rare sight.
Taiwan won't be the only place to see the spectacle. If the weather holds, stargazers in Singapore should be able to see at least a portion of the eclipse. Given Singapore's proximity in time zone, the key phases — including the peak around 7:34 pm Taiwan time — will occur at roughly the same local evening hours in Singapore. The gradual reddening of the moon coincides with lantern displays and temple celebrations, which may intensify the festive mood for astronomy enthusiasts.
Although binoculars or telescopes can offer a more detailed view of the lunar surface as it darkens and changes colour, the CWA stated that no special equipment is needed to view the eclipse. For the best view, especially at moonrise, observers are advised to pick spots with a clear eastern horizon.
For those who are unable to go outside, the CWA will broadcast the event live on its website beginning at 5:40 pm, enabling viewers in Taiwan, Singapore, and other locations to watch the unique astronomical phenomenon in real time.
This year's Lantern Festival promises not only glowing lanterns but also a glowing red moon, as cosmic wonder and cultural customs come together on the same night.
