It's an event that happens a few times every year and is a good chance for photographers to nab a picture of the moon when it appears at its biggest and brightest.
From the Farmer’s Almanac
The Sturgeon Moon The fishing tribes are given credit for the naming of this Moon, since sturgeon, a large fish of the Great Lakes and other major bodies of water, were most readily caught during this month. A few tribes knew it as the Full Red Moon because, as the Moon rises, it appears reddish through any sultry haze. It was also called the Green Corn Moon or Grain Moon.
