Mark your calendars, sky watchers! September 17, 2024, promises a celestial spectacle like no other with a full moon that’s doubled in significance. Not only will it be a supermoon, but it will also wear the title of Harvest Moon, and to top it off, a partial lunar eclipse will add an extra layer of wonder. Strap in as we take a deep dive into the how, when, and where of this extraordinary astronomical event.
The Phenomenal Supermoon
First off, what makes this full moon a supermoon? As the Moon orbits Earth, its path is not a perfect circle but an ellipse. This means that at certain times, the Moon is closer to Earth. When a full moon coincides with this closest approach (or perigee), we get what’s known as a supermoon. The supermoon appears approximately 7% larger and 15% brighter than a typical full moon. On September 17, 2024, at 10:35 p.m. EDT, look up and you’ll see a larger-than-life moon lighting up the night sky.
The Historic Harvest Moon
So, why is it called a Harvest Moon? The Harvest Moon is the name given to the full moon that occurs closest to the autumnal equinox, which falls on September 22 this year. Historically, this moon played a significant role for farmers, providing ample moonlight that extended their working hours well into the night to harvest crops. This was crucial, especially before the advent of modern lighting, making the Harvest Moon an indispensable ally in the agricultural calendar.
The Partial Lunar Eclipse: A Special Treat
Just when you thought the night sky couldn’t get any more fascinating, a partial lunar eclipse will grace the September supermoon. Earth will cast its shadow on the Moon, covering approximately 8% of its surface. The eclipse will begin around 8:40 p.m. EDT and reach its peak at 10:44 p.m. EDT. This celestial event will be visible from various parts of the globe, including North and South America, Europe, most of Africa, western Asia, and parts of Antarctica.
For those in regions where the eclipse isn’t visible or those who prefer a digital view, there are several livestreams available online, such as those from TimeAndDate.com and the Virtual Telescope Project.
Why You Shouldn’t Miss This Event
1. Unique Combination
This isn’t just any full moon; it’s a rare alignment of supermoon, Harvest Moon, and partial lunar eclipse. Such a combination amplifies the celestial spectacle, making it an event that’s not to be missed.
2. Educational Opportunity
For budding astronomers and science enthusiasts, this event offers a fantastic opportunity to learn about lunar cycles, orbital mechanics, and eclipses. It’s a practical astronomy lesson you can enjoy from your backyard.
3. Perfect for Photography
Astrophotographers will find this event a goldmine. The supermoon’s increased size and brightness, combined with the Earth’s shadow creating a partial eclipse, provide an incredible subject for lunar photography.
Preparing for the Show
Ensure you have your calendars marked; the main event starts around 8:40 p.m. EDT with the partial lunar eclipse and peaks at 10:44 p.m. EDT on September 17. While no special equipment is needed to observe a supermoon, having binoculars or a telescope can enhance your viewing experience, especially during the partial eclipse phase.
For those hoping to capture photographs, a camera with a good zoom lens or a telescope with a camera mount will provide the best results. Check weather conditions ahead of time to select an optimal viewing location with minimal cloud cover.
