Supermoons happen each year. They are also called perigee moons because of their marked closeness to the earth compared with other full moons. A perigee moon can appear 14% bigger in the sky and 30% brighter. But to anyone's notice, it really doesn't stand out from any other full moon. Here are some of pictures of the June 23, 2013 Supermoon as it appeared over Gensan, Philippines. It was actually raining during that night, but the skies cleared up a bit and the moon showed itself though briefly. I took the opportunity.
