No, the “Buck Moon Eclipse” on Saturday is not a “blood moon”. That is, why

Only what Iwill the moon continue this Saturday, July 4th, 2020?

There is a lunar eclipse – a “Buck Moon Eclipse” or “Thunder Moon Eclipse” – visible in North and South America, but it’s probably not the kind you think of.

During a “blood moon” – the slang term for a total lunar eclipse– Our satellite takes on a pink-copper-reddish color for a few hours.

This won’t happen on Saturday, however, because the Buck Moon Eclipse is actually a far less visually interesting event – it is Penumbral lunar eclipse.

So what is the difference between a total “blood moon” lunar eclipse and a penumbral lunar eclipse?

It’s a story about the shadow of the earth in space.

What is a total lunar eclipse “blood moon”?

It is when the entire full moon enters the darkest part of Earth’s shadow – its umbra or umbra. A full moon occurs when our satellite is 100% illuminated by the sun, but during a total lunar eclipse, the full moon is almost completely shielded from direct sunlight from the sun.

Why does the moon glow red during a total lunar eclipse?

The only sunlight that reaches the moon comes through the earth’s atmosphere first. This light is filtered by many air molecules in the earth’s atmosphere, which scatter most of the blue light, so that mainly red light reaches the surface of the moon.

But shortly before and after the spectacle of a rust-reddish moon, our satellite moves through the outer shadow of the earth – its penumbra or penumbra. It only loses its brightness and does not change its color.

It is only The Part of a lunar eclipse that occurs on Saturday evening – and Not the “blood moon” part.

What is a penumbral lunar eclipse?

It’s like warming up without the main act. A penumbral lunar eclipse occurs when the full moon crosses into the outer, lighter, fuzzy penumbra of the earth, but does not enter the umbra.

As a visual spectacle, it’s not much to see, although experienced moon watchers can usually notice it. That may not be the case this weekend as only about a third of the full moon will drift into the penumbra of the earth.

While a penumbral lunar eclipse doesn’t offer much cause for joy, it is a great opportunity to snap a great photo of a more subdued full moon.

Is it Safe to View a Penumbral Lunar Eclipse?

This solar eclipse is perfectly safe to watch, the easiest way to see the darkening is through binoculars or a telescope.

So expect a slight weakening of the full “Buck Moon” and no dramatic “Blood Moon” on Saturday evening.

Wish you had a clear sky and big eyes.
