The much-awaited celestial event called Blood Moon or Super Moon will take place in a few hours' time. Skywatchers across the globe are geared up to witness the phenomenon that has spooked celestial soothsayers and triggerred apocalypse theories. However, the rare show will not be visible in all parts of the world, and where it's on display weather could play truant too.

This rare celestial event where the moon appears reddish due to convergence of three lunar events -- total lunar eclipse, full moon nearest the fall equinox, closest approach to Earth for the year -- is called by some as just "Supermoon," while others call it "Blood Moon" and even "Blood Supermoon."

NASA has said in a statement that such an event has taken place only five times since 1900. It last happened in 1982 and is due to happen on 27/28 September (date defers based on location) this year and the next one will happen only in 2033.

Can you see the celestial event?

"Blood Moon" will last for one hour and 11 minutes and can be seen in North and South America, Europe, Africa, and parts of West Asia and the eastern Pacific if weather permits, according to NASA.

Skywatchers from eastern North America can witness the event as the moon rises in the eastern sky, while those from western parts of the continent will see it just after sunset, reported National Geographic. It added that the eclipse will happen in South America during the night time while it will happen in Europe and most part of Africa in the wee hours of Monday, 28 September.

However, the eclipse will not be visible in Asia and Pacific Ocean (West Asia and the eastern Pacific). Unlike solar eclipse, it is safe to watch the show with the naked eye.
