Don't miss the full moon on June 22-23 in 2013

This year, the largest full moon falls on June 23 at 11:32 UTC (6:32 a.m. CDT in the U.S.). For many, the moon appears about as full in the June 22 evening sky as it does on the evening of June 23. This full moon is not only the closest and largest full moon of the year but also presents the moon’s closest encounter with Earth for all of 2013. The moon will not be so close again until August, 2014.
Astronomers call this a perigee full moon. The word perigee describes the moon’s closest point to Earth for a given month. Two years ago, when the closest and largest full moon fell on March 19, 2011, many used the term supermoon, which we’d never heard before. Last year, we heard this term again to describe the year’s closest full moon on May 6, 2012.
Last month’s full moon – May 24-25, 2013 – was also a supermoon but the June full moon is special because the time of full moon falls even closer to the time of perigee, the moon’s closest point to Earth. The crest of the moon’s full phase in June 2013, and perigee, fall within an hour of each other.
 In fact, the June 2013 full moon lines up much more closely with perigee – the moon’s closest point to Earth. According to Guy Ottewell’s Astronomical Calendar 2013, the 2013 June full moon falls only 22 minutes after the moon reaches perigee, the moon’s closest point to Earth for this month and year. At perigee, the moon lies only 356,991 kilometers (221,824 miles) away. Two weeks later, on July 7, the moon will swing out to apogee – its farthest point for the month and year – at 406,490 kilometers (252,581 miles) distant.
Though these might seem to be routine astronomical events, on June 2013 the moon has the closest encounter with Earth until August 10, 2014, at which time the moon will be only five kilometers closer to Earth. The full moon will come even closer to Earth on September 28, 2015 (356,877 kilometers) and closer yet on November 14, 2016 (356,509 kilometers). November 2016 will feature the closest full moon until November 25, 2034!
