Every month brings a full moon. But, a supermoon is when the full moon is at its closest point to earth on its orbit around our planet.
Keep in mind that the moon's orbit is not a perfect circle but is instead elliptical. So, sometimes it's full and far away; other times it's full and closer.
This November's supermoon is particularly rare because it will be the full moon's closest pass to Earth since 1948. And it won't happen again until 2034.
"Hopefully the clouds won't get in the way of our view on Sunday night into Monday morning," WLOX First Alert Meteorologist Wesley Williams said. "Just keep in mind that supermoons are only slightly bigger and slightly brighter in appearance compared to a typical full moon. So, while the view may not be as impressive as you expect, the true significance of this event is really centered around the rarity of its close approach."
