How to watch the Sturgeon moon – the last supermoon of the year

The Sturgeon moon – August's full moon – will take the night sky this week, offering spectators the last supermoon of the year. 

This Sturgeon moon is the considered to be fourth supermoon in a row after the Buck moon in July, Strawberry moon in June and Flower moon in May. A supermoon refers to a full moon when the Moon is within 90% of perigee – its closet approach to Earth. 

Starting in the 1930s, the Maine Farmer's Almanac began publishing Native American names for full moons, NASA said. Based on this almanac, Algonquin tribes that lived in the northeastern U.S. called the full moon in August the Sturgeon moon after the large fish that were more easily caught that same time of year in the Great Lakes.
