Penumbral lunar eclipse: Earth's shadow to fall on moon Friday

Many sky-watchers across America should have a visual look at the full moon and lunar eclipse taking place on Friday, Oct. 18.

A penumbral lunar eclipse  occurs when the faint outer portion of the Earth's shadow falls across the moon. There are three different types of an eclipse: total, partial and penumbral. The effects of a penumbral eclipse are less exciting than that of a total eclipse, but it's still worth taking a look.

The deepest point will be visible beginning at 5 p.m. Arizona time, according to Space .

The visibility of the eclipse is dependent on the weather, but ABC15 forecaster Amy Murphy says we'll have clear skies.

The Hunter's Moon is what we will be seeing Friday night - it's the first full moon after the Harvest Moon. This moon is on it's "ecliptic" path -- meaning that for several nights the moon sits farther north on the horizon which gives it its "glow."

It's been noted that this type of moon got its name because hunters and farmers were better able to see prey in the fields while the moon was shining bright in the sky, according to EarthSky.

Seventy-six percent of the moon will be shaded by the Earth's penumbral shadow during mid-eclipse, said EarthSky

Unfortunately for Arizonans, residents in the Eastern half of North America will have a much better view than those living on the Pacific side. The best show will be visible in Europe, Africa and the Middle East.

Remember, this type of eclipse is very slight, so you will have to look closely to be able to see it.
