According to a report at phys.org, The moon is about to do something it hasn't done in more than 150 years:

Three separate celestial events will occur simultaneously that night, resulting in what some are calling a super blue blood moon eclipse. The astronomical rarity hasn't happened for more than 150 years.

A super moon, like the one visible on New Year's Day, is the term for when a full moon is closest to the Earth in its orbit, appearing bigger and brighter than normal.

On Jan. 31, the moon will be full for the second time in a month, a rare occasion—it happens once every two and a half years—known as a blue moon.

To top it off, there will also be a total lunar eclipse. But unlike last year's solar eclipse, this sky-watching event isn't going to be as visible in the continental United States. The best views of the middle-of-the-night eclipse will be in central and eastern Asia, Indonesia, New Zealand and Australia, although Alaska and Hawaii will get a glimpse, too.

For the rest of the U.S., the eclipse will come too close to when the moon sets for the phenomenon to be visible.

Because of the way the light filters through the atmosphere during an eclipse, blue light is bounced away from the moon, while red light is reflected. The eclipsed moon's reddish color earned it the nickname blood moon.

Super blue blood moon?

So, an extremely noble or socially prominent moon? ;)

I wonder what differences, if any, there would be in the appearance of the Earth from a person standing on the moon, compared to a "normal" full moon?

Daily Telescope: a Solar Eclipse from the Surface of Mars 3 comments

Good morning. It's February 12, and today's image is a real treat from the surface of Mars.

In it we see the larger of Mars' two moons, Phobos, passing in front of the Sun.

[...] NASA released a bunch of these raw images last week, and planetary scientist Paul Byrne helpfully put them into a video sequence that can be seen here.

Here's Our Comprehensive, In-Depth Guide to Viewing the North American Total Solar Eclipse 12 comments

If you enter "how to see the eclipse" into your favorite search engine, you're bound to see thousands—millions?—of helpful guides. Some of these are extremely detailed and thorough, almost as if the author were getting paid by the word or augmented by AI.

In reality, seeing a solar eclipse is just about the easiest thing one can do in one's life. Like, it's difficult to think of anything else that has the greatest reward-lowest effort ratio in life. You just need to know a couple of things. For the sake of simplicity, here is Ars' four-step guide to having a four-star eclipse-viewing experience. Steps are listed in order of ascending importance.

[...] In reality, a total solar eclipse is probably going to be the most spectacular celestial event most of us see in our lifetimes. Certainly, there could be more spectacular ones. A supernova within 100 light-years of Earth would be amazing. Witnessing a large asteroid streaking through Earth's atmosphere before impact would be incredible.

Unfortunately, those would also be lethal.

      For longer than mankind has had the capacity to gaze at the night sky, and wonder about the lights in they sky, that rock has been there, going around, and around, in a slightly eccentric orbit. It doesn't know anything about a recently invented calendar, or blues, or reds, or even about eclipses. It just stays in it's orbit, and does what it is supposed to do - which is nothing. Unless, of course, existing is something.

      Yet, we gaze at that bigass rock, and imagine all sorts of things about it.

      Super blue blood lunar eclipse? Surely, that must be a portent of SOMETHING. Ahhh, yes, it is a portent of confusion and mass hysteria among the naked upright mammals on earth. Nothing to see here, no moons have been harmed, no intelligent creatures have been discomfited.

        Apart from the "blue" part, this hasnothing to do with calendars.

        The "super moon" is related to the excentricity of the moon's orbit. And the "blood moon" is related to the relative alignment of the orbits of earth and moon, and the fact that the earth has an atmosphere which bends light.

    Super: When the Moon is closer to the Earth, the Earth is closer to the Moon. So the person on the moon would see a lightly larger Earth than otherwise (a Super Earth?)

    Blue: That's just a calendar thing; a Blue Moon looks exactly like any other full moon. And the blue Earth will not look different from any other "New Earth" (Earth showing its dark side to the moon) either.

    Blood Moon: Since the red light is shining on the Moon, I expect the person on the Moon would see the ground around him as red lit as well. And of course much darker, due to the solar eclipse. However I'd expect the solar eclipse to be quite spectacular, with the border of the Earth glowing in bright red.

      The redness is highly variable - it is usually more orangey or even yellow-y than red toned (it can also be a dull, burning-ember brick red). Every lunar eclipse I've observed and photographed had a VERY visible change in tone to the tangent point closest to the Earth's surface (for example http://static.snopes.com/app/uploads/2017/02/lunar_eclipse_fb.jpg [snopes.com] ). While there's lots of good speculation as to why, nobody is entirely sure why the variations exist as they do. Lots of good possible explanations have been ruled out. And also remember that the redness is entirely the light we're seeing filtered around the planet (best theory is that light is bent around the earth) and then *also* reflected back at us and again passing through our atmosphere. My guess is that on the lunar surface it would just appear as lunar "night" in terms of dimness, and probably more clearly so than the dimness of a solar eclipse on Earth. But I'm just guessing.

      I wouldn't necessarily expect the border of the earth as bright red.... again because the color is from our perspective and not necessarily theirs, but especially because the Earth covers a much wider swath of the Sun's surface during the lunar eclipse than the Moon does during a solar eclipse. (See https://www.space.com/33786-lunar-eclipse-guide.html [space.com] for an idea of the scale of a lunar eclipse. A total solar eclipse, the moon barely covers the Sun's surface). But I'd expect the same edge-closest-to-sun to have a color variation. (If it's not pitch black and I don't think it necessarily would be).

        The effect of the light going through atmosphere when coming from the moon and heading towards our eye is in no way different from the effect during a normal full moon (or any other moon phase, for that matter). The colour change relative to the normal moon is purely because of the light that reaches the moon.

        The "returning light" effect makes the apparent moon colour dependent on where on the sky the moon is seen (because, just like the sun, the lower the moon is seen, the more distance its light had to pass through the atmosphere). But that's independent of the "blood moon" effect during eclipse.

          I think you're mostly right, and the best theory is that more red-frequency light than blue is able to pass the rim of earth (the same Rayleigh scattering that gives us blue sky I think). There would be a corona around Earth as seen from the Moon (of the same collective color temperature as the moon itself). But I'm also saying don't expect that the surface of the moon around you would appear a blood red color, or even the overall shade your eye perceived when looking at the whole moon from Earth. If you're close to the edge where the tangent is lighting it with more yellow wavelengths, you might see a yellowy surface. If you're at the opposite point it might be duller orange indeed.

          Of all the lunar eclipses I've observed - low in elevation, high in elevation, early evening, midnight, late morning... None of them have been what I'd call red and all of them have had that tangent point of light yellow on one limb. (It's still totally awesome to watch the progression of the eclipse across the lunar surface through a telescope or with imaging. :) ) Others have historically observed exactly that, though. NASA suggests the redness is from the amount of dust in the atmosphere that would scatter the yellow/orange frequencies also. (Same as a dusty sunset...)

          I was also enlightened by both your post and these very interesting pages: https://www.nasa.gov/mission_pages/LRO/news/dec2011-eclipse.html [nasa.gov] and https://svs.gsfc.nasa.gov/4341 [nasa.gov] . Apparently the Lunar Reconaissance Orbiter can't run camera during the eclipse period but did run a Radiometer to measure surface temperature change. And I find it fascinating (though easily understandable) that you get instant lunar "night" temperatures during the eclipse - again on those pages.

      It amazes me that so many allegedly "educated" people have fallen so quickly and so hard for a fraudulent fabrication of such laughable proportions. The very idea that a gigantic ball of rock happens to orbit our planet, showing itself in neat, four-week cycles -- with the same side facing us all the time -- is ludicrous. Furthermore, it is an insult to common sense and a damnable affront to intellectual honesty and integrity. That people actually believe it is evidence that the liberals have wrested the last vestiges of control of our public school system from decent, God-fearing Americans (as if any further evidence was needed! Daddy's Roommate? God Almighty!)

      Documentaries such as Enemy of the State have accurately portrayed the elaborate, byzantine network of surveillance satellites that the liberals have sent into space to spy on law-abiding Americans. Equipped with technology developed by Handgun Control, Inc., these satellites have the ability to detect firearms from hundreds of kilometers up. That's right, neighbors .. the next time you're out in the backyard exercising your Second Amendment rights, the liberals will see it! These satellites are sensitive enough to tell the difference between a Colt .45 and a .38 Special! And when they detect you with a firearm, their computers cross-reference the address to figure out your name, and then an enormous database housed at Berkeley is updated with information about you.

      Of course, this all works fine during the day, but what about at night? Even the liberals can't control the rotation of the Earth to prevent nightfall from setting in (only Joshua was able to ask for that particular favor!) That's where the "moon" comes in. Powered by nuclear reactors, the "moon" is nothing more than an enormous balloon, emitting trillions of candlepower of gun-revealing light. Piloted by key members of the liberal community, the "moon" is strategically moved across the country, pointing out those who dare to make use of their God-given rights at night!

      Yes, I know this probably sounds paranoid and preposterous, but consider this. Despite what the revisionist historians tell you, there is no mention of the "moon" anywhere in literature or historical documents -- anywhere -- before 1950. That is when it was initially launched. When President Josef Kennedy, at the State of the Union address, proclaimed "We choose to go to the moon", he may as well have said "We choose to go to the weather balloon." The subsequent faking of a "moon" landing on national TV was the first step in a long history of the erosion of our constitutional rights by leftists in this country. No longer can we hide from our government when the sun goes down.

I mean, oh noes, if you missed the 2012 Venus transit, there won't be another until 2117! Except, if we want to see a Venus transit that much, we could put a telescope into a place such as the Sun--Venus L2 Lagrange point that would see one constantly.
