Bandar Seri Begawan – People in this country will have a rare opportunity to watch an astronomical phenomenon, a total lunar eclipse, on the evening of this Saturday, April 4th, 2015.

A lunar eclipse occurs when the Moon passes directly behind the Earth and being in the Earth’s dark shadow known as Umbra. Such occurrence is rare when the Sun, Earth and Moon are exactly aligned with the Earth being precisely in the middle.

This great natural phenomenon is also observed by many region around the globe such as Asia, Australia, Pacific, North and South America.

In Brunei, the lunar eclipse will be first observed after the moon rise at 6:22 pm. If the evening sky is clear, eclipse watchers will see the full moon is partially obscured by the Earth’s shadows.

At 7:58 pm, it will be a very spectacular astronomical event as the entire moon will pass through the dark earth`s shadow known as the Umbra. During totality, eclipse observers will notice the full moon to completely darken and likely will turn to coppery red colour.

Totality’s duration is only 4 minutes and 43 seconds when the moon leaves the Umbra at 8.03 pm. Interestingly, the moon passing very close to outer rim of the Umbra will be make this central eclipse being the briefest sight of totality in the 21st century.
