Missed the Supermoon? one more chance in 2013 -- July 22

Another supermoon coming up on July 22

Missed the Supermoon? one more chance in 2013


Yes, in 2013 the moon was closest to Earth at 7:32 a.m EDT on June 23, but you will be able to see the supermoon shining bright on July 22 as well. 

"The July supermoon is actually the third full supermoon to happen in 2013. The first one was in May. Why so many supermoons? The reason is that the definition, as coined by astrologer Richard Nolle has defined a supermoon as:

… a new or full moon which occurs with the moon at or near (within 90% of) its closest approach to Earth in a given orbit.

That’s a pretty generous definition and allows for many supermoons. By this definition, according to Nolle:

There are 2-6 supermoons a year on average.

Tired of supermoons yet? Most people aren't. Like many of the special full moons – such as Blue Moons – supermoons seem to have an unending allure.

This July 2013 full moon presents the second full moon after the June solstice. Normally, there are only three full moons in one season – the period of time between a solstice and an equinox, or vice versa. However, in 2013, four full moons take place in between the June solstice and the September equinox. The third of four full moons to fall in one season will occur in August 2013, and some people will call this particular full moon a Blue Moon.

Next paragraph from http://earthsky.org/tonight/is-biggest-and-closest-full-moon-on-june-23-2013-a-supermoon
"We astronomers call this sort of close full moon 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. Now the term supermoon is being used a lot. Last month’s full moon – May 24-25, 2013 – was also a supermoon. But the June full moon is even more super! In other words, 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. What does supermoon mean exactly? And how special is the June 23, 2013 supermoon?
