What Exactly is a Supermoon?
In simple terms, a supermoon occurs when a full moon coincides with its closest approach to Earth, known as perigee. The moon appears up to 10% larger and shines 30% brighter than a typical full moon. The term “supermoon” was first coined in 1979 by astrologer Richard Nolle and has since been used to describe these visually stunning full moons that hover close to us.
While not an official astronomical term, it's clear why this event captivates so many people. When that giant glowing orb is hanging low in the sky, it feels almost surreal. It’s like the moon has decided to drop in for a closer look at Earth.
Why is This Supermoon Special?
This isn’t just any supermoon. On October 17, 2024, we’ll witness the brightest supermoon of the year, also called the Hunter’s Moon. Historically, this name comes from the time when hunters relied on the post-harvest moonlight to track game across the now-cleared fields. This will be the third in a series of four consecutive supermoons in 2024, but what makes it truly stand out is its luminosity. For three days—from the evening of October 15th to the morning of October 18th—the moon will appear full, with October 17th marking its peak brilliance.
How to Best Observe the Supermoon
Here’s the good news: you don’t need any fancy equipment to enjoy this celestial spectacle. The supermoon will be visible to the naked eye, but if you want to elevate your experience, try watching it just after sunset, around 6:19 PM (in Rome) when the moon is low on the horizon. This is when it will appear the largest and have a beautiful reddish hue, thanks to the scattering of light in Earth’s atmosphere. Just like how the sun looks red at sunrise or sunset, the moon also takes on a similar glow when it’s near the horizon. This phenomenon adds a bit of magical flair to an already impressive sight.
For the best views, find a spot with an unobstructed view of the eastern sky. Rural areas with minimal light pollution will enhance the experience, allowing you to see more details and avoid the washed-out effect city lights can create.
The Science Behind the Color
Ever wonder why the moon looks red during these moments? It’s all thanks to Rayleigh scattering—the same reason we see red and orange hues in the sky during sunrises and sunsets. As the moon hangs low on the horizon, its light passes through a thicker layer of Earth's atmosphere. The atmosphere scatters the shorter blue wavelengths, letting more of the longer red wavelengths reach your eyes. This gives the moon a coppery tint, making it even more breathtaking.
Why Should We Care?
You might be wondering, “It’s just the moon, why all the fuss?” Well, experiencing a supermoon reminds us of how connected we are to the universe. Moments like this give us pause from our busy lives and offer a glimpse into the vastness and beauty of space. Plus, it’s a fantastic excuse to step outside, breathe in the cool night air, and enjoy one of nature’s most accessible shows.
