August’s Astronomical Spectacle: Double Supermoons and a Rare Blue Moon
August is set to stage an extraordinary celestial performance featuring double supermoons and a unique blue moon. These events, characterized by the moon’s close proximity to Earth during its orbit, result in a more luminous and larger-looking moon, offering a breathtaking spectacle for skywatchers.
The First Supermoon and the Sturgeon Moon
The first supermoon of the month is set to peak at 2:32 p.m. ET on Tuesday. This event will offer a stunning view for skywatchers across Europe, the United Kingdom, Africa, and the Middle East. According to retired NASA astronomer Fred Espenak’s calculations, the moon will be approximately 222,158 miles (357,530 kilometers) away from Earth. Interestingly, this supermoon has a unique name. It’s known as the “sturgeon moon.” This name comes from the historical period when large freshwater fish, known as sturgeon, were abundant in the Great Lakes. This period typically coincides with this time of year.
The Second Supermoon and the Elusive Blue Moon
The end of August brings another celestial treat. On August 30, a full moon will appear at its closest point to Earth this year, making it a rare super blue moon. Despite its name, the moon won’t appear blue. The term “blue moon” refers to the occurrence of a second full moon within the same calendar month, a phenomenon that typically happens only once every two and a half years.
Understanding Full Moons, Supermoons, and Blue Moons
A full moon occurs when the moon’s near side is fully illuminated by the sun. Supermoons, on the other hand, occur when the moon is near or at its closest point to Earth while also appearing full. These supermoons can appear up to 14% larger and 30% brighter than regular full moons. Blue moons, however, are rarer and refer to two full moons appearing within the same calendar month.
In a nutshell, the month of August is set to deliver a remarkable astronomical display with double supermoons and a rare blue moon. While these events might not significantly change the moon’s appearance to the unaided eye, they do influence Earth, particularly causing higher ocean tides. So, gear up to enjoy these celestial marvels. The next instance of two supermoons in a single month won’t occur until January 2037.
