A SuperMoon occurs when the center of the Moon is less than 223,694 miles (360,000 kilometers) from the center of the Earth, while the Moon is at 90% or more illumination.
The technical term for a Supermoon is perigee-syzygy of the Earth-Moon-Sun system. In astronomy, the term syzygy refers to the straight-line configuration of three celestial bodies.
A SuperMoon is what we call a “perigee full Moon.” The word “perigee” refers to the Moon’s closest point to Earth in its monthly orbit.
The term 'SuperMoon' didn't even exist until quite recently. And at first, it was used to describe the closest Moon of the year. Then it became the 2 or 3 closest. And now I hear about the '4-6' SuperMoons every year.
When creating my products, I try to work with only the closest Full Moon of the year! I only have a short amount of time and I make as many products as I can, but I am one person (mortal alas LOL), and this is why I highly recommend that you pre-order! 971-255-2868
The Moon has an oval or elliptical orbit, not a round one, which means that every night it’s either a bit closer or farther than it was the night before.
At its closest extreme, the Moon can be 14% closer and thus look 14% larger than at its farthest yearly extreme.
Put another way, it varies 7% from its average size.
Here’s a fact - Nobody can visually perceive a 7% difference in the Moon’s size.
That suits me fine because it's not what I see (obviously), it's the difference in the energies I feel, that become my products!
A SuperMoon can occur during the Dark phase of the Moon as well, though it is not nearly as visually awesome.
Due to its nearness to the Earth, a SuperMoon (during a Full Moon) will look about 7% bigger than the average Full Moon. It will also look about 30% brighter.
AND, SuperMoons during the Winter months look bigger than those occurring during the Summer months.
The best time to enjoy a SuperMoon is just after moonrise (consult almanac.com), when the Moon is just above the horizon. Weather may be inconvenient.
At this position, the SuperMoon will look bigger and brighter than than when it is higher in the sky.
When it is at the level of the horizon, you can compare it to the size of hills, buildings, and such - this effect is called the Moon Illusion.
The next SuperMoon dates are:

When a Full Moon occurs while the center of the Moon is more than 251,655 miles from the center of the Earth (405,000 kilometers), it is called a MicroMoon.
The technical term for a MicroMoon - apogee-syzygy.
Yes, basically all symptoms are the opposite :)
A MicroMoon may look about 14% smaller than a SuperMoon, and it might look a little dimmer (as the illuminated area appears 30% smaller).
A MicroMoon can also occur during the Dark phase of the Moon.
There will be a MicroMoon on December 17, 2017, and again on January 16, 2018.
Then there will be another MicroMoon on July 27, 2018, and then February 4, 2019.
