As the sun begins to set at 8:30pm, the moon will rise and although it will be a few hours before peak illumination it should provide good visibility (weather permitting) about an hour after rise.

Conditions are looking clear, so the moon should be looking fairly bright.

If you live in an area where the horizon is obscured, wait a little longer for the moon to rise higher in the sky around midnight.

What are supermoons?

Supermoons are categorized when the moon is 360,000 km or less from Earth in its orbit.

We will often have two or three full Supermoons in a row.

A super moon appears about 7% larger and 15% brighter than a normal full moon.

A supermoon occurs when the moon is closest to earth along that orbit.

This point is called the perigee. When the moon reaches perigee at the same time as a full moon in the lunar cycle, the moon appears larger in the sky and we get a supermoon.

According to the Natural History Museum’s website, supermoons appear so bright because they “shed approximately 30% more light on the planet than when the moon is at its darkest.”

The reason for this is that the closer the moon gets, the more the sun’s rays, reflected from the moon’s surface, reach the earth.

As for its size, as the supermoon rises and sets on the horizon, it looks bigger, but that’s because of what’s known as the “moon illusion.”

Why is it called “Störmond”?

The Algonquin tribes of North America named the August full moon for the abundance of sturgeons in rivers and lakes at that time of year.

The sturgeon is North America’s largest freshwater fish and is said to be up to six meters long and weighs almost a ton.

They were once abundant but are now in danger of extinction.

NASA explained that the Maine Farmer’s Almanac began printing Native American names for full moons in the 1930s, and those names have stuck.

In Old English, the sturgeon moon was sometimes known as the Barley Moon, Fruit Moon, or Grain Moon.

In China, the full moon in August marks the start of the Hungry Ghost Festival, a traditional festival honoring ancestors and appeasing ghosts.
