On June 23, 2013 we will experience a truly super supermoon. The full moon that falls on June 23, 2013 at 11:32 UTC, will not only be the closest to Earth for the year, but it will also appear the biggest full moon for 2013. It will also be about 30 percent brighter than an average full moon. Last supermoon was on May 24, 2013. And in 2011, we witnessed the moon’s closest approach in 19 years.
Moon`s elliptical orbit is the main reason for the increase in its apparent size. About 50,000 km is the difference between the Moon`s apogee (it`s furthest point to Earth) and it`s perigee (it`s closest point to Earth).
The supermoon of June 2013 will be extra special, as the full moon coincides with it`s closest approach to our planet for 2013, at a distance of 356,991 km. Next time this event will occur is August 2014. It is also worth mentioning that between June 22 and June 25, 2013 the occurrence of “King tides” is expected
