Supermoon????

Today at 2:10pm the moon will be officially full. At 3pm, the moon’s orbit will bring it the closest to earth, known as perigee. Today it will be the closes it has been in 18 years, 221,565 miles away. This will make the moon appear 14% larger and 30% brighter than the lesser full moons, when the moon is farthest from the earth, known as apogee. Thus,the media has labeled it “Supermoon”. However, to the casual observer, it will be hard to tell the difference. To view it with maximum effect, look to the distant horizon making sure you have objects such as mountains or buildings in the foreground. As the moon rises behind these objects, it creates an optical illusion which makes it look even bigger to the naked eye. (See photo) Don’t worry if you miss it, the moon will appear full for several more days. However, never fear, if you don't get to see it now, you’ll get another chance in 19 years.
