Supermoon

On March 19th, the moon was in its perigee - the closest point to Earth in its orbit. This coincided with the full moon, so the moon appeared very large and very bright as it rose on Saturday evening. About two hours after the moon rose, I was able to go out an photograph the moon.


"Saturday's supermoon was just 221,566 miles (356,577 kilometers) away from Earth—making the supermoon about 20 percent brighter and 15 percent bigger than a regular full moon, said Anthony Cook, astronomical observer for the Griffith Observatory in Los Angeles."


Interestingly, the large size of the moon when it rises is all an optical illusion. Try looking at the moon upside down when it looks so large and the illusion disappears. Likewise, when you photograph the moon without zooming in (as I did above using a 400mm lens) you will see it as a tiny dot in your photograph.
