(CBS SF) -- If you missed Saturday's supermoon, don't worry, you ain't seen nothin' yet as the August 2014 supermoon will be the closest the moon comes to earth all year, and should be the best of the five supermoons of 2014 as it passes within 221,765 miles of us.

The next supermoon is on August 10th, with its closest pass at 11:09 a.m. Pacific time, or 6:09 p.m. universal time. The moon rises at 8:01 p.m. in the Bay Area that night, so you'll miss the closest moment unless you're on the other side of the planet, but you won't notice a few miles difference by the time it rises over the Bay that night. Here's a great moonrise and moonset tool.
September 9th is the last supermoon.
The "supermoon" is a relatively newly used term to refer to the "perigee full moon" or new moon, basically, when the moon comes to the closest point in its orbit to earth. "Supermoon" usually refers to any of a number of times the moon orbits earth that fall within the closest 10 percent of orbits.
The three supermoons of summer are the most written about, but Saturday wasn't actually the first. January 1st, 2014, welcomed the new year with the first super moon.
If you want the full astronomy of how it works, EarthSky.org has an amazing amount of diagrams and graphics.
