0 a full moon or a new moon that looks bigger than normal in the sky, because it is at its closest point to Earth
Saturday's event is a "supermoon," the closest and therefore the biggest and brightest full moon of the year.
The supermoon happens once a year when two cycles converge.
Now, astronomers call this a "perigee full moon," which is far less exciting than supermoon.
The terms supermoon was first coined by an astrologer actually and most professional astronomers really cringe at the term.
But the combined supermoon lunar eclipse happens every 30 years or so.
The jaded and moon-weary may scoff and note that we had a supermoon just last month.
Under that umbrella, we really only get a supermoon about once a year.
The next supermoon eclipse will happen in 2033.
