May 15th Lunar Eclipse & what the heck is a Blood Moon anyway?

Super Moon Total Lunar Eclipse by Kenneth Raymond

On the night of Sunday, May 15th, a lunar eclipse will begin at 10:28 pm with total eclipse (when the moon turns red) occurring at 12:11 am. The red cast of the moon at total eclipse has inexplicably become popularized as a “blood moon” in recent years. NASA’s page on viewing the total lunar eclipse gives viewing information & explains why the moon turns red during a lunar eclipse:

The same phenomenon that makes our sky blue and our sunsets red causes the Moon to turn red during a lunar eclipse. It’s called Rayleigh scattering. Light travels in waves, and different colors of light have different physical properties. Blue light has a shorter wavelength and is scattered more easily by particles in Earth’s atmosphere than red light, which has a longer wavelength.

Red light, on the other hand, travels more directly through the atmosphere. When the Sun is overhead, we see blue light throughout the sky. But when the Sun is setting, sunlight must pass through more atmosphere and travel farther before reaching our eyes. The blue light from the Sun scatters away, and longer-wavelength red, orange, and yellow light pass through.

During a lunar eclipse, the Moon turns red because the only sunlight reaching the Moon passes through Earth’s atmosphere. The more dust or clouds in Earth’s atmosphere during the eclipse, the redder the Moon will appear. It’s as if all the world’s sunrises and sunsets are projected onto the Moon.

Leonids + Lunar Eclipse = TONIGHT!

Lunar Eclipse by the Lighthouse by Sathya

If the weather cooperates, tonight & early tomorrow morning hold a whole lot of skywatching potential for Michiganders! In addition to the peak of the Leonid meteor shower, NPR shares the details on tonight’s lunar eclipse:

West Coast night owls and East Coast early risers will have the best view of the upcoming lunar eclipse this Friday. Overnight, the moon will pass into the shadow of Earth cast by the sun, illuminating the gray orb with a red hue.

It will be the second and final eclipse of the year. NASA predicts the eclipse will last over 3 hours and 28 minutes. That would make it the longest partial lunar eclipse in 580 years, according to the Holcomb Observatory at Butler University.

…For U.S. viewers the peak of the eclipse — when the moon is the most covered by Earth’s shadow — will be at 4:03 a.m. ET.

But the moon will begin to pass into the Earth’s shadow much earlier, around 1:00 am ET. At 2:19 a.m. ET the moon will move into the umbra, the inner part of Earth’s shadow, and begin to look like a chunk is missing from it. It will turn red around 3:45 a.m. ET

Sathya shares the story behind this photo from April 2015, saying in part, “Witnessing the lunar eclipse was magical. Planning and shooting the same was a lot of fun. Out here, in the north east of US, the lunar eclipse was not total, so missed out on the blood moon, but it was still a scintillating experience. As the moon was getting into total eclipse, it set over the horizon … This shot is a mix of landscape and time slice – in an attempt to highlight the lunar eclipse in the context of the surrounding landscape. This was a panorama made out of a composite. Though it does not look like a wide view, that is what helped capture the moon and the lighthouse in context.”

October’s Full Moon: a super Hunter’s Blood Moon in eclipse

EarthSky reports that for the full moon on October 8th, there’s a whole lot going on!

In skylore, the Northern Hemisphere’s Hunter’s Moon on October 7-8 will be called a Blood Moon. Plus the October 7-8 total lunar eclipse – the second of four total lunar eclipses in the ongoing lunar tetrad – has been widely called a Blood Moon. Voila. Double Blood Moon.

Hunter’s Moon the name for the full moon after the Harvest Moon, which is the full moon nearest the September 23 autumnal equinox. This year, the Harvest Moon came on September 9. That’s why tonight’s moon bears the name Hunter’s Moon.

…In 2014 and 2015, a new usage of the term Blood Moon sprang up. Surely you heard about it at the total lunar eclipse in April 2014. It’s the name being used for the four eclipses of the ongoing lunar tetrad – four total lunar eclipses in a row, each separated from the other by six lunar months. (more on this on Michigan in Pictures)

The partial umbral eclipse begins at 5:15 AM EDT on October 8, with the total eclipse starting at 6:25 AM, peaking at 6:55 and ending at 7:24.  On top of all that is the question as to whether or not October 8th’s moon is a supermoon:

At least two commentators – Richard Nolle and Fred Espenak – disagree on whether the October 8, 2014 full moon should be called a supermoon. Is it? You’re likely to see all sorts of conflicting information in October, 2014. If you define a supermoon based on the year’s closest perigee and farthest apogee, then the October 8 moon is not a supermoon. If you define a supermoon based on the perigee and apogee for a given monthly orbit, then it is a supermoon. And not just any supermoon, but a super Hunter’s Blood Moon in eclipse!

I guess with Frank’s photo from October 2013, we could add “Sandhill Moon” to the list! He writes that he took this at the Phyllis Haehnle Memorial Sanctuary where counts were as high as eight thousand sandhill cranes a day during last fall’s migration!

Blood Moon kicks off the Lunar Eclipse Tetrad

For as long as we know, celestial signs have been read to signify calamity and change, and apparently the total lunar eclipse in the early morning hours of April 15, 2014 that kicks off a two-year tetrad of lunar eclipses is no exception.

In What is a Blood Moon? on one of my favorite blogs, EarthSky, Bruce McClure and Deborah Byrd explain (in part) a subject you might be hearing about this week:

We’ve been receiving a number of inquiries about Blood Moons in 2014 and 2015. The Blood Moons most people are asking about are not part of astronomy. Their origin is religious, at least according to Christian pastor John Hagee, who wrote a 2013 book about Blood Moons. However, both astronomers and some proponents of Christian prophesy are talking about the upcoming lunar tetrad – a series of total lunar eclipses – which begins on the night of April 14-15, 2014. We at EarthSky don’t have any special knowledge about the purported Blood Moons of Biblical prophesy. But, since they’re moons, and since people are asking us, we wanted to reply.

The full moon nearly always appears coppery red during a total lunar eclipse. That’s because the dispersed light from all the Earth’s sunrises and sunsets falls on the face of the moon at mid-eclipse. Thus the term blood moon can be and probably is applied to any and all total lunar eclipses…

Both astronomers and followers of certain Christian pastors are talking about the lunar tetrad of 2014-2015. What is a tetrad? It’s four successive total lunar eclipses, with no partial lunar eclipses in between, each of which is separated from the other by six lunar months (six full moons)

We’re not experts on prophecy of any kind. But we’ll tell you what we know about the new definition for Blood Moon that has raised so many questions recently.

From what we’ve been able to gather, two Christian pastors, Mark Blitz and John Hagee, use the term Blood Moon to apply to the full moons of the upcoming tetrad – four successive total lunar eclipses, with no partial lunar eclipses in between, each of which is separated from the other by six lunar months (six full moons) – in 2014 and 2015. John Hagee appears to have popularized the term in his 2013 book Four Blood Moons: Something is About to Change.

As if we didn’t have enough to look forward to on April 15th! Read on for lots more. The four eclipses are this one, October 8 2014 and April 4 & September 28, 2015. Here’s the eclipse viewing times for Michigan – times for other time zones can be found on EarthSky.

The April 15th 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.

Eastern Daylight Time (April 15, 2014)
Partial umbral eclipse begins: 1:58 a.m. EDT on April 15
Total eclipse begins: 3:07 a.m. EDT
Greatest eclipse: 3:46 a.m. EDT
Total eclipse ends: 4:25 a.m. EDT
Partial eclipse ends: 5:33 a.m. EDT
