Sky lovers are in for a pleasant surprise tonight as a rare astronomical event will take place in the night sky.
The Harvest Moon, Supermoon, and Partial Lunar Eclipse will occur simultaneously, creating an amazing spectacle that both astronomy enthusiasts and casual observers will not want to miss.
This full moon, known as the Harvest Moon, holds special significance because it is the full moon closest to the autumn equinox. Traditionally, its bright light allowed farmers to work late into the evening, thereby lengthening the harvest season.
The Harvest Moon usually occurs in September, but this year it falls on September 18, just a few days before the vernal equinox on September 22.
Adding to its allure, this Harvest Moon is also a supermoon. A supermoon occurs when the full moon is at its closest point to Earth in its elliptical orbit, known as perigee.
This proximity causes the moon to appear 14% larger and 30% brighter than a typical full moon. Tonight's supermoon is the second in a series of four consecutive supermoons in 2024, making it a relatively rare event.
As if these two factors were not enough to make this lunar event special, viewers will also get to witness a partial lunar eclipse.
Earth's shadow will take a small “bite” at the moon's upper edge, creating a dramatic effect visible across North and South America, Europe and Africa. In India, the eclipse will peak in the early hours of September 18, when about 8% of the moon's surface will be darkened by Earth's shadow.
The partial eclipse will cause the moon to appear reddish, often referred to as a “blood moon.” This happens because Earth's atmosphere scatters blue light but allows red light to pass through, giving the moon's surface a coppery glow.
To best see this celestial trinity, look for a clear view of the eastern horizon around moonrise. Due to an optical illusion, the moon will appear largest when it is near the horizon, making this the best time for viewing and photography.
Although the naked eye is sufficient to enjoy this spectacle, binoculars or a small telescope can also enhance the experience, and details of the lunar surface and the progression of the eclipse can be seen.
Don't miss this opportunity to witness a remarkable night sky event combining a Harvest Moon, a Supermoon and a partial lunar eclipse – a combination that won't happen again for many years.
