Rare Total Lunar Eclipse 'Blood Moon' to Grace Night Sky in the Early Hours of the 8th

(Bandar Seri Begawan, 7th) The Astronomical Society of Brunei Darussalam has issued a statement saying that from late night on September 7th (Sunday) to the early hours of September 8th (Monday), the public will have the opportunity to witness a rare astronomical event, as a total lunar eclipse will appear over Brunei’s night sky.
The society said that when the sun, earth, and moon align perfectly in a straight line, and the moon passes completely through the earth's umbra (the innermost, darkest part of its shadow), a total lunar eclipse occurs.
In Brunei, the lunar eclipse will officially begin at 11:28 p.m., when the penumbra will be cast upon the moon; however, at this stage, the eclipse will be less visible.
When the moon enters the earth’s umbra at 12:27 a.m., the eclipse will become especially pronounced.
As the moon passes through the earth’s umbra, it will gradually darken and turn a deep red color, commonly known as a 'blood moon.'
This red hue is caused by Rayleigh scattering, the same phenomenon responsible for the red color observed at sunset.
The earth’s atmosphere filters and bends sunlight, allowing only longer wavelengths of light to reach the moon.
During the total lunar eclipse, the peak moment will mark the moon’s deepest passage into the earth’s umbra at 2:11 a.m.
If weather permits, this lunar eclipse will offer an excellent opportunity for photography and public observation.
With the total eclipse lasting 82 minutes, observers in Brunei will be able to continuously view all stages of the eclipse.
Such a lengthy total lunar eclipse is truly rare, making this event the most anticipated highlight for astronomy enthusiasts in the past decade.
When the moon leaves the umbra at 2:52 a.m., the total eclipse will end. The partial eclipse will conclude at 3:56 a.m., when sunlight gradually reaches the lunar surface and the earth’s umbra recedes from the moon.
At that time, the full moon is expected to regain its usual brightness at 4:55 a.m.
This will be the first total lunar eclipse seen in Brunei since November 8, 2022. It is expected to be the longest-lasting total lunar eclipse since 2022, with the total phase lasting about 1 hour and 22 minutes, and the entire eclipse lasting over 5 hours.
This lunar eclipse will be visible in Asia, Australia, Africa, Europe, as well as parts of the Pacific and Indian Ocean regions.
Unlike a solar eclipse, a lunar eclipse can be safely observed with the naked eye, and anywhere on Earth where the moon is above the horizon during the eclipse will be able to view the phenomenon.
