You'll have the chance to view a so-called 'supermoon' this weekend.

A supermoon iswhen a full moon or new moon occurs whenit makes its closest pass to Earth. We had a supermoon in March of 2011 as well.

The supermoon will reach its perigee or closest point to Earth at 11:35 p.m. on Saturday.

But experts say you don't have to wait that long. Best viewing is right after the moon rises in the early evening. Experts say try to look at the moon when it's partially obstructed by a tree or other object to create an optical illusion to make the moon look even bigger.

It's the first of six celestial events this month.
