Sturgeon Moon 2025 Raises This Weekend in Canada 

This August, skywatchers are in for a rare celestial treat as the full Sturgeon Moon rises alongside the Perseid meteor shower. While the Sturgeon Moon graces the skies on August 9, the Perseids will peak on August 12-13, 2025, offering a unique opportunity to witness two astronomical phenomena in close proximity.

What Makes the Sturgeon Moon Special?

The full Sturgeon Moon reaches peak illumination on August 9 at 3:55 a.m. EDT, and will be visible for several days surrounding that time. This particular full moon is named after the sturgeon fish, abundant in the Great Lakes during this time of year, and has also been called the Green Corn Moon, Grain Moon, and Wild Rice Moon by various cultures.

In a rare phenomenon, skywatchers will have the chance to see the full Sturgeon Moon rise on two consecutive nights. The moon will rise just after sunset on August 8 and August 9, offering two fantastic viewing opportunities. The best time to catch the full moon is just after sunset when it climbs above the horizon, bathed in the colors of twilight.

Moonrise and the Moon Illusion

As the moon rises near the horizon, it may appear particularly large and orange—a phenomenon known as the “moon illusion.” This optical illusion makes the moon appear much bigger than it does when it’s higher in the sky. The moon’s yellow-orange hue during this time is due to Rayleigh scattering, where shorter blue wavelengths scatter and longer red and orange wavelengths pass through Earth’s atmosphere.

The Sturgeon Moon and Perseids: A Celestial Showdown

Although the Sturgeon Moon will be stunning, its bright light may impact viewing the Perseid meteor shower, which peaks just a few days later on August 12-13. The full moon’s brightness can drown out the faintest meteors, but the Perseids are known for their bright meteors and occasional fireballs, so there will still be plenty to see.

Peter Brown, Canada Research Chair in Planetary Small Bodies, reassures that even with the moon’s brightness, the Perseid meteor shower will still deliver some spectacular sights. Look for bright “earth grazers”—meteors that skim the Earth’s atmosphere and streak across the sky longer than regular meteors. These will be best visible when the radiant point, located in the constellation Perseus, rises in the northeast around 9 p.m. local time.

Best Viewing Tips for the Sturgeon Moon and Perseids

• Time It Right: The best time to observe the full moon is right after sunset when the sky is still glowing with the last light of day. For the Perseids, try to find a spot away from city lights where you can look up freely.
  
• Enjoy the Moonrise: The Sturgeon Moon will rise just after sunset on August 8 and 9, making it easy to catch this stunning view. Be ready with a blanket and a good vantage point!
  
• Watch for Meteor Highlights: Even with the moon’s brightness, the Perseid meteor shower is worth watching. Keep an eye out for bright meteors, fireballs, and long-lasting “earth grazers.”
  

The Full Moon’s Naming Traditions

The full moon in August is often referred to as the Sturgeon Moon in parts of the U.S., named after the sturgeon fish, which are typically caught in the Great Lakes during this time. Indigenous North American cultures also have various names for this moon, with the Green Corn Moon and Wild Rice Moon being significant to many Native American communities.
