Saturday Night’s Celestial Show: The Full ‘Pink Moon’ and a Rare Micromoon

This weekend, skywatchers are in for a treat as April’s full moon, known as the "Pink Moon," rises on Saturday night (April 20, 2024). But there’s an extra twist—this full moon is also a micromoon, making it a unique celestial event.

The Pink Moon: What Is It?

The Pink Moon won't actually appear pink, despite its name. The name comes from Native American customs, specifically from the Algonquin tribe, who named the full moon in April after the wild pink phlox flowers that bloom in the early spring. Other names for this moon include the Sprouting Grass Moon, Egg Moon, or Fish Moon, reflecting seasonal changes.

This is a micromoon for a reason. A micromoon occurs when a full moon coincides with apogee—the point in the moon’s orbit where it is farthest from Earth. The moon may appear slightly smaller and dimmer than usual due to this distance, but the difference is not noticeable to the naked eye. The distance between the Earth and the Moon is about 238,855 miles (384,400 kilometers) on average.

Micromoon Distance: ~252,000 miles (405,500 km)

A supermoon, on the other hand, occurs when the moon is at its closest point (perigee), making it appear larger and brighter.

When and How to Look at It

The Pink Moon will reach peak illumination at 7:49 p.m. EDT on Saturday, April 20 at 23:49 UTC. However, from Friday night to Sunday morning, it will appear to be full, providing numerous viewing opportunities. The moon may appear larger due to the "Moon Illusion" effect just after sunset, so this is the best time to observe it. The moon will be visible to the naked eye, but binoculars or a telescope can enhance details like craters and lunar seas. No special equipment is required.

What is unique about this moon?

While not as dramatic as a supermoon, a micromoon is a fascinating reminder of the moon’s elliptical orbit. In addition, the Pink Moon has cultural significance because it signifies the beginning of spring and has an impact on practices like the date of Easter, which is the first Sunday after the first full moon after the spring equinox.

Last Thoughts Take some time this Saturday to appreciate the Pink Micromoon—a combination of natural wonder, cultural history, and celestial mechanics—whether you're a seasoned stargazer or just enjoy the beautiful night sky. Don’t forget to look up and enjoy the view!

Happy Moon-Gazing! 🌕✨
