The full moon this weekend

From the WGN Chicago's meteorologists FB page of Tom Skilling today:

It's the summer of the "super moon"--or what astronomers call "perigee moons". There are three of them on the way in the months ahead--the first Saturday morning at 6:25 am. Super moons occur when the moon is within 90% of perigee, in other words, within 90% of its closest pass to earth. Though not always easy to see, super moons can be up to 30% brighter and a bit larger than the conventional full moon. Saturday's full moon is known as the Full Buck Moon. NASA has put together a nice video on the "super moon" phenomenon.
