Residents across China will have a rare opportunity to witness a total lunar eclipse in the early hours of September 8, the only such event visible to the naked eye in its entirety from the country this year.
The upcoming lunar eclipse, which occurs when the Sun, Earth, and Moon form a perfect straight line, will commence at 00:27 on September 8. At this time, the Moon will begin to enter Earth's shadow, initiating a process that will last approximately 3.5 hours.
During a total lunar eclipse, the Moon transitions from its usual bright white to a mysterious reddish-copper hue, creating a stunning celestial spectacle.
The lunar eclipse process unfolds through five distinct phases: the beginning of partial eclipse, the beginning of total eclipse, maximum eclipse or totality, the end of total eclipse, and the end of partial eclipse.
As the eclipse reaches totality, the Moon will take on a striking coppery-red color. The most dramatic phase, known as the peak of totality, is expected to occur at 02:12, when the Moon is deepest within Earth's shadow and appears darkest and reddest.
"The red hue of the Moon is caused by sunlight being filtered and scattered by Earth's atmosphere, which bends red light toward the Moon. This is why we see a red Moon during a total lunar eclipse which will last for about one hour and 23 minutes," said Gao Heng, a senior engineer of Yunnan Observatories under the Chinese Academy of Sciences.
The totality phase will end at 02:53, and the entire eclipse will conclude by 03:57, when the Moon fully regains its bright silvery appearance.
This lunar eclipse offers favorable viewing conditions as the full Moon will be at a moderate altitude in the sky.
For optimal observation, it is recommended to avoid city light pollution and find an unobstructed viewing spot toward the southwest. While the eclipse can be enjoyed with the naked eye, those with access to a telescope may enjoy an even more detailed view.
