A Celestial Spectacle: Two Full Moons Light Up South Africa’s Sky in August 2023

In August 2023, South Africans will be able to witness a rare astronomical event: two full moons. The first one, known as the Sturgeon Moon, will occur on August 1, while the second, a blue moon, will grace the sky on August 30.

The Sturgeon Full Moon

The name “Sturgeon Moon” refers to the large sturgeon fish found in the Great Lakes region, which are commonly harvested during this time. Sturgeon fish are vital members of the Great Lakes ecosystem, known for their remarkable size and strength. The reddish hue of the Sturgeon Moon is caused by the interaction of sunlight with the Earth’s atmosphere during this period.

The Blue Full Moon

Contrary to its name, the blue moon does not look blue. It describes the rare occurrence of two full moons appearing within a single month. The blue moon on August 30 will also be a supermoon, meaning it will be closer to Earth than usual, causing it to appear larger and brighter than a standard full moon. This will be the closest supermoon of the year.

Visibility of Full Moons in South Africa

South Africans can witness the Sturgeon Moon peak at 8:31 PM SAST on August 1, while the blue moon will peak at 3:35 PM SAST on August 30. The moons will be visible to the naked eye.

Ideal Locations to Observe the Full Moons

For the best viewing experience, it is recommended to observe both full moons from a dark sky location, where they can be seen in all their glory. Light pollution in cities may affect their brightness.

Origins of Full Moon Names

The full moon names can be traced back to Native American tribes who used them to track seasons. These names reflect the activities and events that occurred during specific times of the year. The Sturgeon Moon is named after the abundance of sturgeon fish in the Great Lakes at this time, while the Blue Moon gets its name from the way it appears in the sky: its proximity to Earth causes a deeper blue hue.

Stargazing enthusiasts can look forward to August 2023, which presents a unique opportunity to witness two extraordinary celestial events. Remember to mark your calendars and venture outside to marvel at the beauty of the night sky during this special month.
