Supermoon to Light Up the Sky for the First Time in 2017

Share

The only supermoon of 2017 occurs this Sunday, Dec. 3rd.

Nichols says that despite the difference between a regular full moon and a supermoon, it is not as grand as it appears.

A supermoon can only occur at perigee-syzygy, when the moon is full and at perigee simultaneously.

While it has been a year since a visible supermoon last lit up the sky, everyone in the world has a chance to marvel at this upcoming full moon.

This weekend's supermoon will be 222,761 miles from Earth, over 16,000 miles closer than its average 238,900 miles. The moon will be closest to the earth in the first hours of the next morning, although it will be a little less full.

The best time to view the supermoon is right after sunset when the so-called "moon illusion" makes the already super-sized moon appear even bigger. According to National Geographic, the supermoon will appear up to 16 percent brighter and seven percent larger than what it normally looks like.

Look to the rising moon Sunday night because it's going to be big - supermoon big. If you choose to watch it live, check what local time you should tune in here.

According to timeanddate.com, supermoons will look about 7 percent bigger than an average full moon (and 12 to 14 percent bigger than a full moon at apogee).

This supermoon won't be quite as special as last year's.

If you're using a DSLR, NASA's senior photographer Bill Ingalls recommends that you use the daylight white balance to adjust for the sunlight being reflected off the moon.

"Tap the screen and hold your finger on the object (in this case, the moon) to lock the focus". The supermoon will still be great as it traverses the sky.

"You can do the experiment with your outstretched thumb". Then do it somewhere else.
