Supermoon

Full Moon at Flamingo Hotel, Las Vegas

The expired postcard US-1895485 was sent to Netherlands on October 2, 2012. It shows a full moon over the Flamingo Hotel on September 30, 2012.

On Sunday, June 23, 2013 at 4:32 am PDT (11:32 UTC / 7:32 am EDT), the moon was at its perigee point, the point in the moon orbit that is closest to the center of the earth. Whenever that happens as the moon also enters its fullest phase, it creates a coincidence called "supermoon". At its fullest and closest, the moon appears about 12% larger in the sky.

In the middle of the picture shows the supermoon in the evening of June 22, 2013 while on the right shows a full moon on September 30, 2012. The difference between the two is shown on the left.

The previous two supermoons happened on March 19, 2011 and on May 6, 2012. The next superMoon will be on August 10, 2014. 

I wish I were in Alaska so that I could see the supermoon in the midnight sun. You can see photos of the supermoon at Huffington Post, Baltimore Sun, EarthSky.ORG and Space.COM.
