Here is a quick look at what’s happening astronomically in August 2015.
The month of August is named after Augustus the first emperor of Rome. He named the month after himself in 8BC.
The traditional full moon name for August is the “Dog Day’s Moon”. The name is derived from the rising of the “dog star” Sirius at dawn. Other names associated with the last full moon of summer are the “Sturgeon Moon”, “Woodcutter’s Moon”, “Green Corn Moon” and “Wort (old-world word meaning plant) Moon”. To the Cherokee it is “the ripe corn moon”. The Oto called it “all the elk call moon”, and for the Zuni it is the “no snow on trial moon”. The Lakota Sioux called it “moon when the cherries turned black”.
