“Coming up this weekend the moon will be full. To be precise, it will be full at Sunday morning at 7:32 EDT. Because of the time that the moon is full, it will basically appear to be just as full Saturday night as Sunday night. At the same time, the moon will make its closest approach to Earth (called lunar perigee) of 2013. Don’t believe the internet hype, the Moon will not appear drastically larger in the sky. The Moon will appear slightly bigger in the sky by a very small amount. It will be difficult to notice the difference without a comparison (see above image).
A new or full moon at 90% or greater of its closest perigee to Earth has been named a “SuperMoon” by astrologer Richard Nolle. This term has made it to the field of astronomy as well as the mainstream media and Richard readily gives credit to us here at AccuWeather Astronomy on Facebook for helping this occur.
Please visit Richard Nolle’s fascinating page by clicking here. His page is full of interesting information and I highly recommend it.
An extreme “Supermoon” is when the moon is full or new as well as at its 100% greater mean perigee (closest) distance to earth. By this definition, the Supermoon this weekend will be an extreme “Supermoon”. This Supermoon will pass 356,991 km away from the Earth. In comparison, the March 2011 Supermoon passed 356,575 km away and the average distance between the Earth and the Moon at any particular time is 384,400 kilometers.
A Supermoon is not a rare event. In fact, there are several Supermoons by definition each year. An extreme Supermoon is a rarer event, occurring about every 13 or 14 months. The next extreme Supermoon will be in August of 2014.” Mark Paquette
