Strawberry Moon 2024: Skywatchers To Have A Celestial Treat On June 21; Everything You Need To Know!

As the longest day of the year passes and summer settles in, skywatchers have a celestial treat to look forward to. The full moon on June 21, known as the "Strawberry Moon," promises to be a mesmerizing sight, offering a trifecta of visual delights: size, colour, and an unusually low position in the sky. Here's what to expect from this year's Strawberry Moon and why it's an event not to be missed.

This year's Strawberry Moon is set to rise on Friday, June 21, the day following the summer solstice. It will reach its full phase precisely at 9:08 pm EDT, marking the first full moon of the summer season. However, the moon will appear full for about three days, from Thursday evening through Sunday morning, according to NASA's lunar expert, Gordon Johnston.

Skywatchers across the United States are in for a visual treat as the moon ascends in the southeastern sky soon after sunset. The Old Farmer's Almanac encourages enthusiasts to look towards the southeast at dusk to witness the moon emerging on the horizon, where it will appear larger and with a golden hue.

The Strawberry Moon earns its reputation for being one of the most colourful and visually striking full moons of the year. Bob Bonadurer, the director of the planetarium at the Milwaukee Public Museum, explains that this vivid display is due to the moon's low trajectory across the sky. The low arc forces moonlight to travel through more of the Earth's atmosphere, scattering shorter wavelengths and allowing the longer wavelengths (reds and oranges) to dominate. This effect, known as Rayleigh scattering, gives the moon its characteristic golden or amber glow.

Adding to its allure, this full moon will be the lowest of the year, peaking at just 21.9 degrees above the southern horizon at 1:20 am on Saturday. This phenomenon is referred to as the "Moon Illusion," where the moon appears larger when it is close to the horizon compared to when it is higher in the sky. This optical illusion occurs because our brains perceive the moon's size differently based on its position relative to the horizon.

Despite its moniker, the Strawberry Moon won't appear red or resemble a strawberry. The name "Strawberry Moon" actually has roots in the agricultural practices of Native American tribes. The Algonquin tribes of the northeastern United States, along with the Ojibwe, Dakota, and Lakota peoples, named this moon after the strawberry harvest season in June. This period marked the perfect time for gathering ripened strawberries, a vital seasonal activity.

The naming tradition was popularized by the Maine Farmer's Almanac in the 1930s, which began publishing Native American names for full moons. These names often reflect natural phenomena or important seasonal events. In Europe, the June full moon is also known by other names such as the Mead Moon, Honey Moon, and Rose Moon, each highlighting different cultural associations with this time of year.

To fully appreciate the Strawberry Moon, it's best to find a location with a clear view of the southeastern horizon. Urban areas with tall buildings or dense tree coverage might obstruct the view, so open spaces or higher ground are ideal. The golden colour will be most pronounced shortly after the moon rises and again before it sets, making the early evening and pre-dawn hours prime viewing times.

For those with telescopes or binoculars, the Strawberry Moon provides an excellent opportunity to observe lunar surface features, such as craters and maria, in greater detail. The low angle of the moon's rise and set can also enhance the three-dimensional appearance of these features due to the angle of the sunlight hitting the lunar surface.

The Strawberry Moon is not just a visual spectacle but also a reminder of the interconnectedness of natural cycles and cultural traditions. As you gaze at the golden-hued moon rising on June 21, you're witnessing the same celestial event that has been observed and celebrated for centuries by various cultures around the world.
