The “Pink Moon” is a popular term for a specific full moon, and its name often sparks curiosity about its appearance. This article aims to clarify what the Pink Moon truly signifies and its visual characteristics. Understanding the origins and observations of this lunar event provides deeper insight into both natural phenomena and cultural heritage.
Its Actual Appearance
Despite its evocative name, the Pink Moon does not appear pink in the night sky. Like any other full moon, its color can range from white, grey, or silver when high in the sky.
When the moon is low on the horizon, it takes on golden, orange, or even reddish hues. This phenomenon is due to the scattering of light by Earth’s atmosphere. As moonlight travels through more of the atmosphere when the moon is low, shorter blue wavelengths of light are scattered away, allowing longer red and yellow wavelengths to reach our eyes. This atmospheric effect can make any full moon appear warmer in color, and it is not unique to the Pink Moon.
The Origin of Its Name
The name “Pink Moon” originates from traditional Native American cultures, particularly the Algonquin tribes. This full moon is named after the Phlox subulata wildflower, commonly known as moss pink or creeping phlox.
This plant is one of the earliest widespread flowers of spring in eastern North America, blooming profusely around this time and carpeting the ground with pink flowers. The Maine Farmer’s Almanac began publishing these traditional moon names in the 1930s, contributing to their widespread recognition.
Other traditional names for this moon include the Sprouting Grass Moon, the Egg Moon, and the Fish Moon, reflecting various natural occurrences during early spring.
Best Ways to Observe
To best observe the Pink Moon, look for it shortly after moonrise or before moonset. At these times, the moon is low on the horizon, and the atmospheric scattering effect can make it appear larger and more colorful.
Finding a location with an unobstructed view of the horizon and away from city lights can enhance the viewing experience. While no special equipment is needed to appreciate the moon’s beauty, binoculars can provide a more detailed view of its surface features. Observing the moon during its full phase can reveal features like ray ejecta systems, which are bright streaks radiating from craters.
