The full Moon names used by The Old Farmer’s Almanac have different origins, including Native American, Colonial American, and European sources. Traditionally, each full Moon name was applied to the entire lunar month in which it occurred, not solely to the full Moon.
The Sturgeon Moon
The name Sturgeon Moon comes from the giant lake sturgeon of the Great Lakes and Lake Champlain; this native freshwater fish was readily caught during this part of summer and an important food staple for Native Americans who lived in the region. At one time, the lake sturgeon was quite abundant in late summer, though they are rarer today.
What Is a Sturgeon?
These prehistoric-looking fish have been traced back to around 136 million years ago, and many people call them “living fossils.”
- Females require around 20 years to start reproducing, and they can only reproduce every 4 years. However, they can live up to 150 years!
- Today, there are about 29 species worldwide, including the lake sturgeon found in the Great Lakes. They have evolved in size from the size of a bass to a monster sturgeon as big as a Volkswagen.
- The lake sturgeon is quite rare today, due to intense overfishing in the 19th century, pollution, and damage to their habitat.
Alternative August Moon Names
Flying Up Moon is a Cree term describing the time when young birds are finally ready to take the leap and learn to fly.
Corn Moon (Algonquin, Ojibwe), Harvest Moon (Dakota), and Ricing Moon (Anishinaabe) signify that this is the time to gather maturing crops. Along the same vein, the Assiniboine people named this period Black Cherries Moon, referring to when chokecherries become ripe.
The Tlingit people of the Pacific Northwest traditionally called this time of the season the Mountain Shadows Moon.

I encourage you to make friends with people from all corners of the globe. Get our your telescopes and grab a notebook. Observe the night sky together. Learn constellations as this will help to orient you. As you make observations together, you will begin to form a clear understanding of the spherical earth.
...get *out your telescopes
Yes thats life and especially in todays world of fake pictures and narrative. What can be believed is a better response
Okayyyyyyyy seems like you need to do your research
Smh 🤦🏼♀️
You need to get out of the house a little more often.
I'm sittin here at 9:01pm an everybody says it looks like there's 2 of em in the sky tonight like almost what it might look like if u were seeing double it looks really cool..
I just wanna know the moon will be in Seattle. Too many lights at night. And buildings
Seattle is not a good place for viewing the wonders of the night sky. I always enjoyed going to Sunrise Point in Mount Rainier National Park for the best night sky viewing. The Perseid meteor shower peaks on Aug 12 and Aug 13 this year and is expected to be spectacular this year with up to 100 meteors per hour. I suggest you start planning an overnight trip to the park for a real treat. I have never been disappointed by the Perseids when viewed from Sunrise Point. However you should plan on arriving early to get a parking spot as well as to not disturb others' viewing pleasure with bright car lights.
