DENVER (CBS4) – The second of three supermoons this summer will be visible over the weekend.

It’s called a supermoon because it will be full at perigee, or the point when the moon is closest to the Earth — more than 31,000 miles closer — in its monthly orbit.

This month, according to, the moon will be 221,931 miles from Denver at perigee, or just more than 700 miles closer than it was in July and will be in September, making it the biggest supermoon of 2014.

The moon will appear much larger than normal, especially on the horizon. It will be full at 12:09 p.m. mountain time on Sunday, Aug. 10.

The August full moon was sometimes called the Sturgeon Moon by Native Americans in and near the Great Lakes because the sturgeon fish were so easy to catch this time of year.

It’s also known as the Red Moon, the Green Corn Moon and the Grain Moon.

If you happen to miss the weekend’s supermoon, don’t worry, you will have one more chance to see it this year.

September’s full moon will also be a supermoon. It will happen at 7:38 p.m. on Sept. 8, 2014.

The only difference is it won’t appear quite as big as it will this month.
