And yet, last month's full moon, on Jan. Even some reputable astronomy sites endorse this definition. To the casual stargazer, a supermoon looks similar to other full moons. If you step outside and look at the moon on Tuesday night and expect to see something special, you'll likely be disappointed. At least last month's so-called supermoon was accompanied by a total lunar eclipse. Still, tons of images are posted to the internet in advance of a supermoon, depicting exceedingly large, full moons from images taken with telephoto lenses, implying that the moon is going to look amazingly large in the sky.
At its closest on Tuesday, the moon will be , miles , km from Earth. But that's only 7. So, while Tuesday's moon will indeed be the "biggest" in apparent size, unless you catch the moon when it's either rising or setting — and appearing briefly larger than normal because of the famous "moon illusion" — Tuesday's full moon will look pretty much like any other full moon.
Full moon on Tuesday will occur at a. EST GMT — during the daytime, with the moon below the horizon — so Americans will not get to see the exact moment that the moon is full. When the moon comes above your local horizon on Tuesday evening, technically you'll be looking not at a "full" moon, but a waning gibbous moon. Though a full moon theoretically lasts just a moment, that moment is imperceptible to ordinary observation. And so, for a day or so before and after the moment of full moon, most will speak of the nearly full moon as being "full.
Then, there is the issue of the moon's brightness. Some think that they will see an exceptionally dazzling full moon come Tuesday night. Back in , a friend of mine told me that she was expecting year's version of the supermoon"to look "radically brighter Some websites, including Spaceweather.
But that comes out to a minuscule increase of less than three-tenths of a magnitude ; the moonlight on Tuesday night will not be exceptionally bright. About the only effect of Tuesday's supermoon that we'll be able to notice directly is its influence on the tides. The near coincidence of Tuesday's full moon with perigee will result in a dramatically large range of high and low ocean tides. Any coastal storm at sea around this time will almost certainly aggravate coastal flooding problems. Such an extreme tide is known as a perigean "spring" tide , the word spring deriving from the German "springen," meaning to "spring up.
The supermoon's influence on tides is explained by a simple physics equation. Tidal force varies as the inverse cube of an object's distance from the ocean. On Tuesday, the full moon will be The most literal meaning of blue moon is when the moon not necessarily a full moon appears to a casual observer to be unusually bluish, which is a rare event.
The effect can be caused by smoke or dust particles in the atmosphere, as has happened after forest fires in Sweden and Canada in and ,  and after the eruption of Krakatoa in , which caused the moon to appear blue for nearly two years.
Taurus (April 20 - May 20)
Helens in and Mount Pinatubo in On September 23, , several muskeg fires that had been smoldering for several years in Alberta, Canada, suddenly blew up into major—and very smoky—fires. Winds carried the smoke eastward and southward with unusual speed, and the conditions of the fire produced large quantities of oily droplets of just the right size about 1 micrometre in diameter to scatter red and yellow light. Wherever the smoke cleared enough so that the sun was visible, it was lavender or blue.
Ontario, Canada, and much of the east coast of the United States were affected by the following day, and two days later, observers in Britain reported an indigo sun in smoke-dimmed skies, followed by an equally blue moon that evening. The key to a blue moon is having lots of particles slightly wider than the wavelength of red light 0.
It is rare, but volcanoes sometimes produce such clouds, as do forest fires. Ash and dust clouds thrown into the atmosphere by fires and storms usually contain a mixture of particles with a wide range of sizes, with most smaller than 1 micrometer, and they tend to scatter blue light. This kind of cloud makes the moon turn red; thus red moons are far more common than blue moons. The following blue moons occur between and These dates use UTC as the timezone; exact dates vary with different timezones. Using the Maine Farmers' Almanac definition of blue moon meaning the third full moon in a season of four full moons, but referenced to astronomical rather than equal seasons , blue moons have occurred or will occur on:.
Unlike the astronomical seasonal definition, these dates are dependent on the Gregorian calendar and time zones. Two full moons in one month the second of which is a "blue moon" : .
At that time there will be a total lunar eclipse. There are more modern songs, like Beck 's " Blue Moon.
In the paranormal romance fiction novel by Laurell K. Hamilton of the same name, Blue Moon refers to two full moons occurring within the same month.zesthitoloole.ml
