How to fully enjoy 2017's only supermoon


But supermoons would even more rare if the moon didn't precess. Perigee syzygy has occurred three previous times in 2017. The moon should sit near the constellation Taurus, though it shouldn't be hard to spot.

A supermoon, of course, is no bigger than the moon at any given time, but the term refers to when a new or full moon coincides with the lunar orbit coming in close proximity to Earth, according to National Geographic.

The previous supermoon was the closest to Earth since 1948, and we won't see another like that until 2034. The Moon takes about 27.32 days to orbit Earth.

Now, the sky will light up at exactly 6.06 pm on Sunday, December 3rd, providing a dazzling display overhead. How big will it be? Most astronomers suggest watching the supermoon right after sunset and into moonrise, and minutes before the next sunrise as well. However, the moon will still appear plenty big when it rises in the eastern sky Sunday evening.

Make sure to look up on Sunday night to catch the only supermoon of 2017. The best time to watch a supermoon is when it's low, near the horizon.

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

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.

"The supermoon gets headlines because the moon's a little bigger and a little brighter, but people get frustrated that they can't always tell the difference". The supermoon will still be great as it traverses the sky. Then do it somewhere else.
