An Amazing Lunar Eclipse Coming Soon & It Will Turn The Moon Red! More Details Inside...

Any time there is an eclipse of the moon or sun that is visible in our area, I make an effort to see it. I find these events very cool and everyone in our area will have the chance shortly! This will not be the only lunar eclipse visible over the next two years in what NASA calls an "extraordinary series of lunar eclipses" called a "tetrad of lunar clipses". NASA has a interesting article about this phenomena and how often the tetrad occurs...

 

A Tetrad of Lunar Eclipses


March 27, 2014:  For people in the United States, an extraordinary series of lunar eclipses is about to begin.

The action starts on April 15th  (tonight) when the full Moon passes through the amber shadow of Earth, producing a midnight eclipse visible across North America. So begins a lunar eclipse tetrad—a series of 4 consecutive total eclipses occurring at approximately six month intervals.  The total eclipse of April 15, 2014 (tonight), will be followed by another on Oct. 8, 2014, and another on April 4, 2015, and another on Sept. 28 2015.

"The most unique thing about the 2014-2015 tetrad is that all of them are visible for all or parts of the USA," says longtime NASA eclipse expert Fred Espenak.


A new ScienceCast video explains the lunar eclipse tetrad of 2014-2015.
 
 

 

On average, lunar eclipses occur about twice a year, but not all of them are total.  There are three types:

A penumbral eclipse is when the Moon passes through the pale outskirts of Earth’s shadow.  It’s so subtle, sky watchers often don’t notice an eclipse is underway. 

A partial eclipse is more dramatic.  The Moon dips into the core of Earth’s shadow, but not all the way, so only a fraction of Moon is darkened.

A total eclipse, when the entire Moon is shadowed, is best of all.  The face of the Moon turns sunset-red for up to an hour or more as the eclipse slowly unfolds.

Usually, lunar eclipses come in no particular order. A partial can be followed by a total, followed by a penumbral, and so on.  Anything goes. Occasionally, though, the sequence is more orderly. When four consecutive lunar eclipses are all total, the series is called a tetrad.

"During the 21st century, there are 9 sets of tetrads, so I would describe tetrads as a frequent occurrence in the current pattern of lunar eclipses," says Espenak. "But this has not always been the case. During the three hundred year interval from 1600 to 1900, for instance, there were no tetrads at all."

The April 15th (tonight) eclipse begins at 2 AM Eastern time when the edge of the Moon first enters the amber core of Earth’s shadow.  Totality occurs during a 78 minute interval beginning around 3 o’clock in the morning on the east coast, midnight on the west coast.  Weather permitting, the red Moon will be easy to see across the entirety of North America.

Why red?

A quick trip to the Moon provides the answer: Imagine yourself standing on a dusty lunar plain looking up at the sky. Overhead hangs Earth, nightside down, completely hiding the sun behind it. The eclipse is underway.

You might expect Earth seen in this way to be utterly dark, but it's not. The rim of the planet is on fire! As you scan your eye around Earth's circumference, you're seeing every sunrise and every sunset in the world, all of them, all at once. This incredible light beams into the heart of Earth's shadow, filling it with a coppery glow and transforming the Moon into a great red orb.

Mark your calendar for April 15th (tonight) and let the tetrad begin.

Weather For Tonight's Lunar Eclipse...

 

I do want to be very clear, the weather will be terrible tonight and there is zero chance of seeing the lunar eclipse for our area. I know a lot of people were looking forward to it, but unfortunately the weather will not cooperate.

Thanks for posting, Marc! I've got my calendar set!

Excellent essay. Thank you --seeing all sunrises and sunsets around the globe at the same time. What an amazing thought!

Carroll, I just wish we could see it tonight. :(

The blood red moons are all apart of Biblical Prophecy,especially the 4 that will occur
