The Only Supermoon of 2017 Is This Weekend—Here's How to See It

Sky watchers patiently waiting for the moon to go big this year will finally be rewarded in a couple of days as the only supermoon of 2017 will finally appear on Dec. 3.
A "supermoon" takes its name from the especially large appearance of the moon, which happens when a full moon happens at the same time when the moon reaches its perigee, the point in its orbit when closest to Earth. The resulting view makes the moon appear approximately 14-percent larger and about 30 percent brighter than usual. On this occasion, the moon will go fully "Full" at 10:47 a.m. EST on Sunday, December 3, then reach its perigee December 4 at 3:45 a.m. EST. 
Of course, while its popularly referred to as a supermoon, if you're speaking with a scientist they will likely refer to this event as "perigee-syzygy," as this event involves the alignment of the Moon, Earth, and Sun.  

Chances are if you see the supermoon and it looks as cool as you hope, you might be tempted to take a photo of this lunar show—and as most of us can (or should) admit, pics rarely show the dynamic view that we caught with our eyes. 

Last year, when the full moon of November 14, 2016 was the closest supermoon in almost 70 years, the media attention was somewhat pitched, and NASA responded with some advice from one of its senior photographers on how to best snap a shot.
