What is a Supermoon? And why is it such a big deal for skywatchers?
The Moon’s orbit is elliptical, taking it from 362,600 to 405,400 km from the Earth in the course of its 27.55 day orbit from one perigee (closest point) to the next. So when the moon is closer to us in it’s orbit, it does appear to be slightly larger than when it’s farther away. When we experience a full moon near the point of perigee, we see an apparently larger moon than usual. You can read more about Supermoons, and the interesting physics that make them in David Dickinson’s article “November’s Supermoon 2016 – Closest of a Lifetime?” over on Universe Today.
The Supermoon on Nov. 13 was the closest that the full moon will be to perigee for the next 80 years.
Some of you may have had the good fortune to observe this Supermoon. If you didn’t, we’d like to share some of the loveliest views from the internet.

And as just a little bit of comic relief, if you couldn’t see the Supermoon, you could always do this:
