Mark Your Calendars: Rare Supermoon Blue Moon to Occur on August 19

Astronomy enthusiasts are in for a celestial treat on August 19, 2024, as one of the year’s most impressive lunar displays takes center stage. A rare combination of a Supermoon and a Blue Moon, an event that occurs only a handful of times per century, will light up the night sky.

This exceptional full moon, traditionally known as the “Sturgeon Moon” in August, will appear unusually large and bright due to its close proximity to Earth during its full phase. This proximity is what earns it the “Supermoon” moniker.

Decoding the Blue Moon Phenomenon Contrary to its name, a Blue Moon doesn’t actually appear blue. The term has two distinct definitions in modern astronomy. The traditional definition, which applies to this event, refers to the third full moon in a season that has four full moons. The alternative definition, born from a misinterpretation but now widely accepted, describes the second full moon within a single calendar month.

Gordon Johnston, a former NASA Program Executive, explains, “The term ‘Blue Moon’ has a rich history dating back to 1528 in English usage. Its origins are debated, with theories ranging from an old English phrase meaning ‘betrayer Moon’ to rare instances where atmospheric conditions actually tint the moon blue.”

Viewing Guide for the Celestial Event The Blue Supermoon will grace the skies on August 19, remaining visibly full for approximately 72 hours. Peak fullness is expected at 11:56 pm IST on Monday.

For optimal viewing, experts recommend finding a location with minimal light pollution and an unobstructed view of the horizon. The moon will be most prominent as it rises in the southeastern and eastern sky.

While visible to the naked eye, telescopes or binoculars can enhance the experience by revealing more lunar surface details. Observers are advised to allow time for their eyes to adjust to the darkness, with color vision improving after about 10 minutes and black-and-white vision continuing to sharpen for up to an hour.

October 17 will showcase the Hunter’s Moon, set to be the year’s closest full moon. The final supermoon of 2024 will occur on November 15.

This rare Blue Supermoon offers a unique opportunity for both casual stargazers and dedicated astronomers to witness one of nature’s most awe-inspiring displays. As we look to the skies on August 19, we’re reminded of the vast wonders that unfold in our cosmic neighborhood.
